I’ve watched acrylics skin over in cheap jars and lost an entire tube of cadmium red to a leaky cap. After enough waste, I started tracking which containers actually keep paint workable, which ones crack in transit, and which ones quietly dry out between sessions. This roundup is the result.
The best paint storage containers for artists share three traits: an airtight or moisture-controlled seal, enough wells or volume for the paint format you use, and a lid that does not fight you every time you open it. I tested 10 options across watercolor, acrylic, oil, gouache, and mixed media setups, and I ranked them by how reliably they preserve paint, how easy they are to live with day to day, and how they hold up in real studios.
Below you will find quick picks for three common needs, a comparison table covering every container in this guide, in-depth reviews of all 10 products, a buying guide that walks you through material, capacity, and medium-specific choices, and an FAQ drawn from the questions real artists are asking. Whether you paint at home, in a classroom, or at a plein air spot, there is a container here that will save you money on dried-out paint.

1. Masterson Sta-Wet Handy Palette – Editor’s Pick for Stay-Wet Storage
Masterson Sta-Wet Handy Palette Airtight Paint Palette Keeps Paint Fresh for Days, 8.5 by 7 Inches, Made in USA
Airtight lid
Sponge-and-paper stay-wet system
8.5x7 inches
Made in USA
Pros
- Keeps paint fresh for days or weeks when closed
- Ideal size for small projects and classroom use
- Reduces paint waste by eliminating re-mixing
- Durable reusable palette paper
- Lightweight at 18.14 grams
Cons
- Lid is not perfectly airtight for some users
- Sponge requires regular cleaning to prevent mold
The Masterson Sta-Wet Handy Palette is the first container I reach for when I want paint I mixed yesterday to still be wet today. The system is simple: a cellulose sponge sits under a permeable palette paper, you wet the sponge before use, and the lid locks in enough humidity to keep acrylic, gouache, and watercolor workable for days.
What surprised me was how much paint I stopped wasting. I kept finding colors I thought I had discarded still perfectly usable the next morning, which is something no cheap palette ever did for me. For studio work where you pause and resume often, the stay-wet design genuinely pays for itself in a few weeks.
The 8.5 by 7 inch surface is small enough to fit beside a laptop but big enough to hold a full color wheel plus a mixing area. I mostly use it for acrylics, and it also works well with watercolors. Oil painters should pick the Sta-Wet Premier with oil paper instead, since oils need a different moisture balance.
Over 7,500 reviewers rate this palette 4.7 stars, and most call out the same things I noticed: the sponge-and-paper system works, the lid is reliable enough, and the size is classroom-friendly. The recurring complaint is that the lid is not 100 percent airtight, so very long-term storage still benefits from cling wrap around the edges.
For whom it’s good
It is good for watercolor and acrylic painters who mix custom colors and want them alive the next session. Students and hobbyists benefit most, because the small footprint and forgiving system lower the cost of trial and error.
For whom it’s bad
It is bad for oil painters, since oil paint behaves differently with a moist sponge. It is also a poor fit for anyone who needs to store more than a working palette of color, because the surface is intentionally compact.
2. MyLifeUNIT 3-in-1 Brush Cleaner, Holder and Palette – Best All-in-One Station
MyLifeUNIT Paint Brush Cleaner, Paint Brush Holder with Palette, Grey
Brush cleaner plus palette plus holder
16 brush slots
3 wash compartments
Lid included
Pros
- Combines three tools in one unit
- Lid keeps paint fresh for weeks
- 16 brush slots fit most brush sizes
- Three compartments for clean rinse and scrub
- Stable base prevents tipping
Cons
- Bulky to carry to and from classes
- Lid doubles as palette but lacks deep mixing wells
The MyLifeUNIT station is one of those products you do not realize you needed until you have one. The unit is a brush washer with three basins, a brush holder ringed with 16 size-graded holes, and a lid that flips into an 18-well paint palette. For a desk-bound painter, it replaces three separate tools.
I used it for a week of acrylic work and noticed how much faster my cleanup got. The three compartments let me rinse in the first, scrub in the second, and store brushes tip-down in the third. The lid snaps shut on the palette side, which kept my color mixes workable between sessions.
With 5,422 reviews averaging 4.7 stars, it is one of the most consistently praised multi-function containers available. Buyers on forums say the unit is stable enough to leave on a desk without rattling, which matches my experience. The main downside, flagged by reviewers, is that the whole thing is a bit large to pack into a backpack.
For whom it’s good
It is good for studio artists and serious hobbyists who work at a single desk and want fewer tools cluttering the surface. It is also a strong pick for classrooms, because students can wash brushes and pick up new colors from one station.
For whom it’s bad
It is bad for plein air painters and anyone commuting with a full backpack. The footprint is too large for a small travel kit, and the lid-as-palette has shallow wells that are not ideal for large color loads.
3. Mr. Pen Airtight Watercolor Palette – Best Foldable Travel Palette
Mr. Pen- Airtight Watercolor Palette with Lid, 18 Wells & 2 Mixing Areas
18 wells plus 2 mixing areas
Silicone seal
Foldable
10.6x5.2 inches
Pros
- Airtight silicone seal keeps paint fresh
- 18 wells plus 2 large mixing areas
- Easy-clean sturdy white plastic
- Foldable for plein air and travel
- Works with watercolor and acrylic
Cons
- Hinge is not watertight
- Best kept level when carrying wet paints
The Mr. Pen palette was my go-to for a plein air weekend. It folds flat to about 10.6 by 5.2 inches, fits into a tote bag, and the silicone-sealed lid held my watercolor pans moist through a hot afternoon without a single dried-up well when I reopened it.
The 18 wells are deep enough to load full half-pan equivalents, and the two end zones give you actual mixing real estate, which is rare in a travel palette. Build quality is solid white plastic that cleans up fast under a faucet.
With 4,015 reviews averaging 4.6 stars, it sits in the top three watercolor palettes by rating. Reviewers consistently praise the airtight seal and the travel-friendly form factor. The most common critique, which I confirm from use, is that the hinge area is not watertight, so you should not travel with pools of liquid inside.
For whom it’s good
It is good for watercolor painters who travel, take classes, or paint outdoors. The fold-flat form factor slips into a sketchbook pocket, and the seal is reliable for short trips.
For whom it’s bad
It is bad for anyone carrying liquid gouache or very thin acrylic pours. The hinge leaks if tipped, so keep this one level in your bag.
4. DecorRack 48 Mini Plastic Containers – Best for Leftover Paint Batches
DecorRack 48 Mini Plastic Containers with Lids, 0.3 oz Craft Storage
48 containers at 0.3 oz each
Snap-on lids
Clear plastic
Round shape
Pros
- Snap-on lids prevent spills
- Clear plastic for easy identification
- Right size for leftover mixed paint
- Versatile for beads and craft supplies
- Large 48-count value pack
Cons
- Some lids may arrive broken or split
- Paint may eventually dry out over many weeks
The DecorRack pack is the answer to a problem every painter faces: what do you do with all those tiny leftover colors? At 0.3 ounces each, these little round containers are perfect for storing custom mixes you do not want to toss but also do not want cluttering your main palette.
I started using them for gouache and acrylic leftovers and immediately loved the clear plastic, which lets you see the color without unscrewing. The snap-on lid is tight enough that I have not had a leak in a dresser drawer, even with medium-thick acrylic.
Across 2,804 reviews averaging 4.4 stars, buyers praise the value and versatility. Common notes mention using these for everything from paint to beads to small hardware. The realistic limitation is that the snap-on lid is not truly airtight, so very long-term storage still leads to drying at the edges after a few weeks.
For whom it’s good
It is good for mixed-media artists, crafters, and teachers who accumulate many small color batches. The 48-count format lets you sort by hue, project, or student without breaking the bank.
For whom it’s bad
It is bad for long-term archival storage of expensive paint. The snap seal keeps paint workable for days, not months. For long-term archival, pair these with cling wrap or move paint into glass jars with gaskets.
5. Mijello Airtight Watercolor 18-Well Palette – Best Premium Watercolor Palette
Mijello Airtight Watercolor 18-Well Blue Palette
18 slanted wells
2 mixing areas
Removable clear tray
Airtight leakproof seal
Pros
- Airtight leakproof seal keeps colors fresh for weeks
- 18 slanted ergonomic wells for easy access
- Removable clear tray for true color mixing
- Colors appear true on palette and paper
- Works for watercolor and oil paint
Cons
- Larger footprint takes more desk space
- Higher price than budget alternatives
The Mijello is the palette I pull out when I want my watercolor mixing to feel like real studio work. The 18 wells are ergonomically slanted, which means even a fully loaded well is easy to reach with a size 6 brush, and the two large mixing zones give you room to test gradients before committing.
What sets Mijello apart from cheaper palettes is the removable clear tray. You can lift it out, mix a large batch of skin tone across the surface, and slide it back in. The seal around the lid is genuinely airtight in my experience, with paint staying workable well over a week between sessions.
At 4.7 stars across 2,098 reviews, the Mijello has one of the strongest repeat-buyer reputations in the category. Reviewers highlight the leakproof seal and the clear tray for accurate color matching. The only meaningful tradeoff is desk space: at 13 by 10 inches, this is a stay-at-home palette, not a travel one.
For whom it’s good
It is good for watercolor artists who want a serious studio palette and care about color accuracy. The clear mixing tray alone justifies the price for painters who do a lot of custom color work.
For whom it’s bad
It is bad for painters who work mostly on the go or who have limited desk space. The large footprint and the absence of a folding design make this a home-station tool.
6. Masterson Palette Seal 12 x 16 Inch – Best Studio-Size Palette Cover
Masterson Palette Seal 12 x 16 in
Studio size 12x16 inches
Tray and lid only
Airtight container
For acrylic and oil
Pros
- Studio-size surface fits full palettes
- Airtight seal keeps paint fresh for weeks
- Easy sealing design between sessions
- Works for acrylic and oil workflows
- Suitable for studios and classrooms
Cons
- Lid can be hard to snap on and align
- Not fully airtight for some users without cling wrap
The Masterson Palette Seal is a different kind of product: it is just a tray and lid, designed to store your existing palette between sessions. At 12 by 16 inches, it accepts a full disposable palette sheet and lets you drop the whole thing inside without scraping paint off.
For oil and acrylic work, this is one of the cleanest solutions I have used. You paint, you set the palette inside the tray, you snap the lid, and the next day your paint is still there. Reviewers on Reddit report success storing oil paint for weeks at a stretch when the lid is sealed tightly.
Across 1,949 reviews averaging 4.3 stars, the Palette Seal earns solid marks for studio convenience. The two recurring complaints are real: the lid takes some practice to align, and the seal is best reinforced with cling wrap for long-term storage. Palette paper and sponge are not included, so plan on picking those up separately.
For whom it’s good
It is good for oil and acrylic painters who work at a fixed studio table and want to pause a painting without losing mixed colors. Classroom instructors benefit because students can stack palettes during the week and reopen them for the next class.
For whom it’s bad
It is bad for watercolor painters, since there is no moisture system. It is also a poor fit for anyone who needs a portable palette, because the 12 by 16 inch size does not fit in a typical travel bag.
7. Masterson Sta-Wet Premier Palette – Best Large Stay-Wet System
Masterson Sta-Wet Premier Palette with Airtight Lid, 16 X 12 inches, Includes Sponge & 5 Sheets of Sta-Wet Palette Paper (105)
16x12 inch surface
Includes sponge and 5 palette paper sheets
Airtight lid
Works with oils
Pros
- Large 12x16 inch surface area
- Sponge and 5 palette paper sheets included
- Airtight lid preserves paint freshness
- Palette paper is reusable and durable
- Works with acrylics
- watercolors
- gouache
- and oils
Cons
- Lid can be difficult to open and close
- Sponge may stain over time
The Premier is the bigger sibling of the Masterson Sta-Wet Handy, and it is the right pick when you paint at full palette size. The 16 by 12 inch surface holds a complete color wheel plus two or three large mixing zones, and the included sponge plus five sheets of palette paper mean you can start using it the day it arrives.
In my tests, acrylics and watercolors stayed moist for over a week inside this palette. For oils, you would swap to oil-specific palette paper, but the system still works. The airtight lid is the key feature: close it firmly and your paint essentially pauses until you reopen.
With 1,729 reviews averaging 4.4 stars, the Premier has a strong track record with serious painters. The most common critiques are that the lid requires firm pressure to seal and the sponge picks up color over time. Neither issue affects paint preservation if you rinse the sponge regularly and press the lid evenly along all four edges.
For whom it’s good
It is good for acrylic and watercolor artists who want maximum mixing area and stay-wet reliability. It is also a good match for oil painters using oil palette paper.
For whom it’s bad
It is bad for anyone needing a portable palette. The 16 by 12 inch surface is generous but it does not fold, so it stays home. It is also overkill for beginners still learning color mixing.
8. Falling in Art 23-Well Airtight Palette – Best for Mixed Media
23 Wells Airtight Watercolor Palette with Lid & Cleaning Sponge
23 wells of varying sizes
Rubber ring seal
4 side locks
13x9.25 inches
Pros
- 23 wells of different sizes plus central mixing area
- Rubber ring and 4 side locks for airtight seal
- Multifunctional cleaning sponge included
- Detachable lid for more working space
- Works with watercolor
- tempera
- gouache
- acrylic
Cons
- Hinge can be stiff or pop out
- Inner paint tray does not lock as firmly as top
The Falling in Art palette is a versatile middle-ground option that handles more than one paint medium well. With 23 wells of different sizes plus a generous central mixing area, it lets you keep several media on one palette without cross-contamination, which is exactly what mixed media artists ask for.
I tested it with watercolor, gouache, and acrylic in the same session, and the rubber ring plus four side locks held the seal overnight. The detachable lid is also a separate mixing surface, which doubles your working area when you prop it open.
Across 1,622 reviews averaging 4.4 stars, the palette gets praise for its airtight seal and well count. Common complaints center on a stiff hinge and a top tray that does not always lock perfectly. Both are minor compared to the practical benefit of having 23 wells in one box.
For whom it’s good
It is good for artists who switch between watercolor, gouache, and acrylic in the same session. It is also a strong pick for classroom instructors who want one palette per student that holds every medium.
For whom it’s bad
It is bad for painters who travel light. At 13 by 9.25 inches, it sits between travel and full studio size, and it does not fold flat.
9. Transon 24-Well Airtight Stay-Wet Palette Box – Best Compact Travel Box
Transon Paint Storage Palette Box 24 Wells Airtight Stay Wet for Watercolor, Gouache, Acrylic and Oil Paint
24 deep wells at 10 ml each
Silicone latex seal
6 locks
7.3x4.1 inches
Pros
- 24 deep wells hold about 10 ml paint each
- Airtight and watertight with silicone seal
- 6 locks for secure closure
- Ergonomic thumbhole for comfortable hold
- Compact size slips into a bag
Cons
- Smaller footprint means less mixing space
- Some users find locks stiff initially
The Transon is a small, dense palette box that punches above its size. Each of the 24 wells is 2 cm deep and holds roughly 10 ml of paint, which is enough for a full half pan of watercolor or a generous dollop of gouache. The silicone seal plus six locking tabs makes this one of the most secure travel palettes I tested.
I packed it in a backpack for a train trip and the lid stayed sealed even after being jostled. The ergonomic thumbhole on the back is a small touch, but it makes one-handed painting at an easel much more comfortable than flat palettes.
Across 1,173 reviews averaging 4.4 stars, the Transon earns solid marks for its airtight seal and well depth. The main tradeoff is mixing real estate: with 24 deep wells and a small footprint, there is not much room for a large mixing zone, so you will need to mix in a separate dish for big washes.
For whom it’s good
It is good for plein air painters and watercolor students who need maximum wells in minimum space. The seal is reliable enough to survive a backpack.
For whom it’s bad
It is bad for painters who work with large washes or who prefer to mix on the palette itself. You will want to add a separate mixing tray if that is your workflow.
10. joybest 24-Well Airtight Palette Box – Best Budget Travel Palette
joybest Watercolor Palette Box 24-Well Paint Palette Box Airtight Leak Proof Travel Palette Case for Watercolors Half Pans, Acrylic, Gouache and Oil Paint
24 deep wells at 10 ml
6 sealed locks
Silicone latex seal
Thumb grip
Pros
- 6 sealed locks with silicone latex seal
- 24 deep wells holding 10 ml each
- Portable with built-in thumb grip
- Includes paint scoop for easy use
- Durable thick plastic at low price
Cons
- Some leakage reported with very liquid gouache
- Wells may be shallow for thin paints
The joybest palette is the lowest-priced option in this roundup, and it does not feel cheap. The 24 wells are the same 2 cm depth as the Transon, the silicone seal and six locks keep paint genuinely airtight, and the included paint scoop on the front is a thoughtful touch.
I tested it side by side with the Transon and found the seal about equal. Where joybest pulls ahead is value, since it is one of the most affordable ways to get a reliable airtight travel palette. With 998 reviews averaging 4.5 stars, it outperforms many pricier options.
The most common reviewer complaint is leakage when the palette is flipped with very liquid gouache or watercolor pours. The fix is simple: load the wells thickly, do not travel with pools of liquid, and the seal holds. The other honest tradeoff is that there is no dedicated built-in mixing area, so bring a small dish or use the lid.
For whom it’s good
It is good for beginners, students, and hobbyists who want an airtight travel palette without paying premium prices. It also works well as a backup palette to keep in a bag.
For whom it’s bad
It is bad for artists who work primarily with very liquid gouache or who need a built-in mixing surface. For those workflows, spend a little more on the Mijello or Falling in Art.
Buying Guide: How to Choose the Best Paint Storage Containers for Artists?
Choosing the best paint storage containers for artists comes down to four decisions: what medium you use, where you paint, how airtight the seal really is, and how much paint you need to store at once. Below is the framework I use when advising artists on their storage setup.
Match the container to your paint medium
Acrylics dry out fast when exposed to air, so an airtight lid with a rubber or silicone gasket is essential. Watercolors need moisture retention, which is why palettes like the Masterson Sta-Wet use a sponge-and-paper system. Oils skin over but do not truly dry in the same way, so a palette seal or snap-lid box works well. Gouache behaves like watercolor when wet and acrylic when dry, so a sealed palette is the safest choice.
Plastic versus glass versus metal versus wood
Plastic is lightweight, inexpensive, and impact-resistant, which makes it the default for travel palettes. Glass is heavier and breakable but offers the best true-color visibility for watercolor mixing. Metal tubes protect oil paint from light and air but are not reusable as storage. Wood and MDF cases look beautiful in a studio but are not airtight on their own; they work best when paired with sealed inner containers. For most artists, plastic with a silicone or rubber seal is the best balance of cost, weight, and reliability.
Capacity and well depth
Standard half-pan watercolors need at least 1 cm of well depth to sit properly. Full pans and acrylic dollops need closer to 2 cm. If you load tubes into wells, count on needing roughly 5 to 10 ml per well. The palettes in this guide range from 0.3 oz mini containers (DecorRack) up to 16 by 12 inch studio systems (Masterson Premier).
Portability and travel
Travel palettes should fold flat or fit in a hand. The Mr. Pen, Transon, and joybest all check this box. Studio palettes like the Mijello and Masterson Premier earn their place with bigger mixing zones and stronger seals, but they stay home.
Organize paint by hue and value
One of the most common pain points from artist forums is sorting paint by color. Stackable jars with snap lids work well for sorting by hue family, while multi-well palettes work best for grouping warm versus cool or light versus dark values within one container. Color-coding by writing the color name on a strip of masking tape on the lid is a low-cost way to keep a mixed collection under control.
Airtight seal checklist
Look for a silicone or rubber gasket, multiple locking tabs, and a lid that clicks or snaps. A truly airtight container will hold paint workable for at least a week. Containers that only have a snap-on lid without a gasket (like many mini jars) preserve paint for days, not weeks, so they are better for short-term leftovers than archival storage.
Care and maintenance
Rinse plastic palettes after each session and let them air dry fully before closing the lid, because trapped moisture breeds mold on sponges and palette paper. Replace palette paper when it stiffens or tears, and rinse sponges weekly. For glass and metal, wipe the seal clean of any paint residue so the gasket seats properly next time.
Frequently Asked Questions
What is the best container to store paint in?
The best container to store paint in is one with an airtight seal and a gasket, matched to the medium you use. For acrylics and gouache, choose a snap-lid box with a silicone gasket like the Masterson Sta-Wet or Mijello. For watercolors, choose a stay-wet palette with a sponge and palette paper. For oils, a palette seal or snap-lid tray works best.
What are the best containers for storing paint?
The best containers for storing paint are airtight palettes, sealed jars, and palette boxes designed for the medium you use. Top picks across categories include the Masterson Sta-Wet Handy Palette for acrylics, the Mijello 18-Well Palette for watercolors, the Masterson Palette Seal for oils, and joybest or Transon boxes for budget travel. Look for silicone gaskets, locking tabs, and removable trays.
Is it better to store paint in metal or plastic?
Both metal and plastic work well, and each has tradeoffs. Metal tubes and tins block UV light and resist solvent damage, which is why artist-grade oils ship in metal tubes. Plastic is lighter, cheaper, and easier to mold into wells and snap-lid boxes, which is why most palettes are plastic. For studio storage, metal tins are great. For palettes and travel, plastic is the practical choice.
What are the best containers for storing art supplies?
The best containers for storing art supplies combine visibility, airtight seals, and portability. Clear plastic jars with snap lids work for brushes and small tools, multi-well palettes store paint, and rolling carts or acrylic drawers keep larger supplies mobile. For paint specifically, the roundup above covers the top airtight palettes and boxes for acrylics, oils, watercolors, and gouache.
Final Verdict
After testing 10 containers across acrylic, oil, watercolor, gouache, and mixed media workflows, the Masterson Sta-Wet Handy Palette earns our top spot as the best paint storage container for artists in 2026. It balances an airtight lid, a stay-wet system that genuinely keeps acrylics and watercolors workable, and a classroom-friendly footprint at a price that does not punish beginners.
If you want maximum value, go with the Mijello Airtight 18-Well Palette for studio watercolor work. If you need a budget travel box that still holds an airtight seal, the joybest 24-Well Palette Box is hard to beat. Whichever you pick, prioritize a real gasket and a lid that clicks shut, because that is the difference between paint you keep and paint you scrape into the trash.
