NEW Super Pro Sta-Wet Palette by Masterson - The multi-purpose palette for acrylics, oils or watercolors. For acrylics, use the patented Sta-Wet palette paper and sponge (five sheets and one sponge included). Moisten the sponge, then place a barrier sheet over it. Paints slowly absorb moisture from the sponge, keeping them workable for hours while the palette is open. For watercolors, 28 separate wells hold pigments, with 3 divided mixing areas. Use the inverted lid as an additional large mixing area. For oils, remove the acrylic palette paper and sponge. Place a paper oil palette (not included) in the tray. The lid keeps paint clean and retards drying. 15-1/2- x 11-1/2 x 1-1/2-inches.
