No more wasted paint. . . Mastersons patented process keeps acrylics and other waterbased 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 wet sponge and special permeable palette paper provide the paint with a constant source of moisture. Paints will not dry out! Simply soak the palette in water until it is fully saturated. Saturate the sponge and place it in the tray. Lay the palette paper on top of the sponge, wipe off excess water from the paper, and put your paints on the wet paper. The paints will slowly absorb moisture as needed without changing the consistency or color value. You can mix paints on the wet paper without tearing it.
