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

I bought this variation on the Masterson Sta-Wet palette product line, as the one I had before, did not work well after awhile. It was more for watercolor or oil, I'm thinking.This particular palette states very clearly in the instructions that if you are keeping acrylic paints, it is recommended that you use their sponge and paper for acrylic. I did not heed that recommendation.All I have to say is WOW! I kept several colors locked up tight in this palette(Purchased 27 May 2025) and opened it today, 20 June 2025. All of the paints were still wet and workable. The mixed areas were dry, but that happens no matter what you do. I am SOLD.I would advise that you make sure to snap the lid tightly. When you think you have it, press lightly in the middle. If you hear air whistling, you need to push it down all the way around.Couldn't be happier with this product.

I keep my palette paper pad and "in use" oil paints in this sealable container. It works really well. I have had no problems with the fit of the lid or the seal. I did initially apply some Vaseline to the lid with a Q-tip, and marked the corners of the lid and bottom left corners with a sharpie so that I always have the same top and bottom corners aligned the same way. Works beautifully - have had zero issues.I also put this palette box in the freezer for days between my paint sessions, which extends the life of my oil paint and has saved me tons of money. I do let it warm up for about 15 minutes though, before opening and using.

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.

I was surprised at how long it was able to keep my paints fresh. Highly recomended

Keeps paints wet for days...with sponge and paper as suggested.

It's important to remember this is a "Palette SEAL," although it can be used as a palette. Here's why I ordered this, and how I use it:During an oil painting workshop a few weeks ago, the instructor used a piece of glass duct-taped (on the edges) over a same-sized piece of luan board that was painted neutral gray. At the end of class each day, he simply put the glass inside this palette and sealed it. You can use a paint scraper (w razor blade insert) to scrape off any paint that dries on the glass and a good scraper doesn't damage your glass palette. So, I can have a sizable, fairly easy to clean glass palette with a neutral gray background. Oil paints won't stay fresh "forever," but they will stay good for several days. My palette is about a quarter inch smaller all around than this SEAL to make it easier to remove the glass. If you cut the glass the exact same size, it would be pretty impossible to get it out of the palette without tipping the whole thing over.Even if you're using acrylics, using a glass palette makes sense because you never have to worry about staining the white surface of this palette SEAL. Just put a damp sponge in with your glass palette, to keep the acrylics moist. You can also just put a paper palette in the seal but the bottom surface isn't conducive to just one sheet of palette paper. You can put the entire pad in the SEAL and remove the top sheet when you're finished with it.Obviously this won't work for people who need to hold the palette, but for those of us who paint while seated, or with our palette within easy reach on a table, the "glass over neutral gray board," works wonderfully.BTW the instructor had one palette with duct tape (gray side out) covering the luan board, instead of paint! Is that easy, or what?I haven't tried putting the entire palette in the freezer overnight, because the seal works well enough for me. I'm concerned the plastic will become brittle if frozen, plus I just don't have enough freezer space at this time of year.

I hate this thing. I was taking an advanced oil painting class and the teacher wanted everyone to get this box since it was a multiple day class and we were leaving the paints there overnight so I ordered it. I followed instructions and even marked my left corner as indicated. It was a little difficult to close but no big deal. Day 1 of class … Neither the teacher nor me could get the top on at the end of the day. The sides just won’t line up and pop on. Of course, I marked the left corner and it also has some paint on the side so I cannot return it. A total waste of money! And something I thought I could use for years gets to pollute the landfills. Disgusted by the poor quality.

I was so excited and I paid for the sponges the paper and this container that was a lot of money to find out that I still have to put something heavy on top of the lid.And yes, the paint was drying out, even though I’m putting weight All around the edges of this product.Please note it shows up sealed, but once you take that lid off it no longer works properly
