Masterson Sta-Wet Acrylic Palette Paper keeps acrylics and other water-soluble paints moist and workable for days and even weeks by evenly distributing moisture from the Sta-Wet Sponge to your paints. The paper is permeable, cleanable, and reusable. Please note, traditional palette paper does not provide the same moisture wicking effect but does the opposite by creating a barrier that locks out moisture.  Traditional palette paper cannot be used with the Sta-Wet system.
