Masterson Aqua Pro Watercolor Palette
No more wasted paint. . . Masterson's patented process keeps acrylics and other water-based paints moist on the open palette for hours. Once the lid is closed, the paints will stay in workable condition for days, even weeks. A unique sponge and special permeable palette paper provide the paint with a constant source of moisture. Paints will not dry out.
