Review on Stainless Portable Cleaning Container Watercolor by Amy Mcleod

I bought it to use when traveling and to paint in nature with my watercolor set. It's really well made and securely attaches to my drawing board, palette, or magazine. I fill both cups with water so I can use one side for the first dive and the other side for the last "clean" dive. Holds the perfect amount of water for a magazine page or two, but if you're doing a serious or extensive watercolor painting you'll need to keep pouring and refilling these tumblers. To avoid this hassle, I also take a large (collapsible) water cup with me.
