The Masterson Sta-Wet Super Pro Palette is a multi-purpose paint palette for all painting media such as acrylic paint, watercolor paint, and oil paint. Join the thousands of artists, students, instructors, and hobbyists who choose Masterson Art Products for all their palette and paint storage needs. When the Sta Wet Super Pro Palette is being used as a palette for acrylic painting, use Masterson's Sta-Wet system. Wet the special permeable paper and sponge and place them in the bottom of the box. Paints will slowly absorb moisture from the sponge, keeping paints wet for hours while the palette is open. With the lid closed, water-miscible paints will stay wet for days, even weeks! The Masterson Super Pro features 28 separate wells for holding pigments and 3 divided mixing areas to keep your color ranges separate. When using the Super Pro Palette for watercolors, remove the paper and sponge to free all the wells and mixing areas, so they are available for mixing. The inverted lid can be used as an additional, larger mixing area. Closing the lid will keep paints clean between painting sessions. When using the Super Pro as a palette for oil painting, remove the acrylic palette paper and sponge. Insert your favorite oil painting palette (not included) into the Masterson palette box. The lid will keep your paints clean and slow drying.
