I was checking brushes on the site when I ran across this palette. I was surprised by the low price, and how convenient it looked. I ordered, and am so glad that I did! I will be using it as a travel palette for watercolors. The palette is made of a sturdy plastic, has 18 wells and each well holds about a half teaspoon of paint. There are 3 mixing areas: a divided space between the wells, a clear, sturdy plastic insert that sits in the top and lifts out easily, as well as the inside of the top itself. Before putting in any paint, I did a quick check, and found that paint beaded up a little on the mixing space; so quickly wiped it with some toothpaste and rinsed it off. The paint now puddles well and flows on the surface nicely. There is a waterproof gasket around the edge. Mine is not totally watertight, but it will help while in transit and, like every other palette I've used, will need to be transported flat. It is about 5" x 10 1/2" and about 1" thick. So glad I purchased this.
