Masterson Sta-Wet Acrylic Palette Paper keeps acrylics and other water-soluble paints moist and workable for during your painting session by evenly distributing moisture from the sponge to your paints. The paper is semi-permeable, which will keep your paints hydrated without watering them down.
Use distilled water to wet sponge and paper when setting up your palette to avoid odor during storage.
