The Sta-Wet Super Pro Palette by Masterson can be used to store and preserve your paints including acrylics, watercolors and oils. The Super Pro features 28 separate wells for holding pigments and 3 divided mixing areas to keep your color ranges separate. Use the inverted lid as a larger mixing area and to keep paints clean between sessions. For acrylics use Mastersons patented Sta-Wet palette paper (1216.1) and sponge (1216.51) (not included) to keep paints moist when not is use.
