No more wasted paint! The Masterson Sta-Wet Handy Palette keeps acrylics and other water-based paints wet on the open palette for hours. Once the lid is closed, the paints will stay wet and in workable condition for days, even weeks. The airtight acrylic palette features a patented sponge insert and special permeable palette paper. Together, they provide acrylics and other water-miscible paints with a constant source of moisture. Moisten the sponge and lay it inside the paint palette tray, then place the palette paper on top. When the lid is open, the paints will have an extended open time. When the lid is snapped shut, the Masterson Sta-Wet palette will maintain a moist atmosphere that preserves paints. In addition to its uses with water-based paints, the Sta-Wet palette can be used as an oil paint palette. For use with oils, simply remove palette and sponge and use the covered paint palette to store oil paints (oil palette paper not included). The lid has five prongs that provide structural stability and prevent any paints stored inside from contact with the lid. The Handy Palette is the ideal size for projects in the studio or classroom, and the small size also makes it great for travel.
