MastersonArtist Palette Seal, 12in x 16in Airtight Palette Container, Keeps Wet Paint Fresh for Weeks, Oil or Acrylic Painting Palette with Lid, Seal, Blue Lid Box, Made in USA

My original rating was a mistake. I am VERY pleased with the Stay-Wet pallette. It is easy to use and keeps my paints fresh for 2 weeks. It's easy to clean and set up for your next painting session. I love the design and I have plenty of room to mix colors. The paper is strong enough to handle mixing with a paint spatula as well. I absolutely love this product and it wasn't overpriced.

Excellent Product. Keeps Paint fresh for days. I recommend this product

This works perfectly for my glass palette which measures precisely 16” x 20”. It actually has just a little wiggle room from side to side, so the inner dimensions are a tad bigger than advertised. I made a little pull that I can lift it up with by using a little electrical tape stuck on the back.The lid is very airtight. I store it in the fridge and my paint blobs and smears stay soft and useable for at least a couple days (longest I’ve gone so far).Lid is very easy to put on and take off, as long as you follow the included directions. Ironically, the instructions are held captive inside the box……so how does one easily open it?? Pop up the four corners first, then the sides will easily release. I don’t know about you, but I usually tend to release one corner then try to pull it off, and it usually works, but not so well with this box. Uss the four-corners-first method for this one!Also just so you know it says not to store it in the freezer because it can become brittle and lead to cracking. I store it in the fridge and it works well.Thanks for reading my review…I hope it helps you

Maybe it delays drying by a little bit, maybe the paint might last until the next day. But for the super fast drying paints like Prussian blue, they're still dry the next day, even after totally sealing the container all around the edges according to the instructions given. I feel that the seal is tight, but there's enough air still on the inside after it's sealed that it still dries out the paint regardless. If it makes a difference, I use paper palettes rather than the glass one that some people use, so maybe paper takes up less space leaving more room for air to still be inside. It might be good to save paint if you have to go to bed and want it to still be wet the next morning, but after 2-3 days, the paints (other than the slow drying ones like yellow) will still be drying up as if you just left them out normally. I was really hoping for something where I could paint, take a break for 2-3 days, and come back with the paint still usable, but this is not the case.Also, sealing the container tightly is a pain (literally very painful on the hands to press on the lid hard enough to properly seal it going around every inch of the edge) and it makes so little of a difference in drying speed that at this point, I don't even seal the lid and it's just a nice palette holder. It's still good as a palette holder and nicely fits a 12x16 inch palette, it does slow drying somewhat, but it did not slow drying nearly as much as I had hoped.

Love this watercolor palette! I use it to keep my oil paintings that are small while traveling back and forth from my painting class. While in class, I use it to put down palette paper or wax paper to put my oil paint and Liquin on.The cover does keep my oil paint dry if I have any left.

I have worn out two of these. I love them. Keeps oil paint moist for days

This has no seal that snaps in place. The lid came warped and there are gaps. Even if the lid wasn’t warped it would be eventually because it’s made of flexible rubber material. Cheap.

It's a great concept, but like many others...I found it a pain to try and seal. I did the marking of the corner thing, and it is still a struggle. Tupperware is not a new concept, so why can't we have a lid that just snaps on? Vaseline the grooves? It feels like we have to do a lot to make the product work, when it should have just been better designed and produced. It works if and when you can get it to seal completely.
