No more wasted paint! Masterson's patented palettes will keep acrylics and other water-based paints moist for days, even weeks. A wet sponge and special permeable palette paper provide the paint with a constant source of moisture, so paints will not dry out. Directions: Soak palette paper in water until fully saturated. Saturate sponge and place it in the tray with the palette paper on top. Wipe off excess water from the paper and put paint on the wet paper. Paint will slowly absorb moisture as needed without changing the consistency or colour value. You can mix paints on the wet paper without tearing it. Four Sta-Wet palette sizes and types available.
