Save paint, time and money using the Masterson Palette Seal. This airtight container safely holds any type of paint palette between sessions. (Paint palette not included.) For oils, place your favorite type of palette - wood, glass, plastic or paper - into the Palette Seal tray and snap on the lid. Your paints will stay fresh for many days, even weeks when they're sealed in the airtight Masterson Palette Seal. For acrylics and other water-miscible paints, use Masterson's patented Sta-Wet Premier Acrylic Paper and Sponge (sold separately). The sponge, when moistened and combined with Masterson's Acrylic Palette Paper, maintains a moist "atmosphere" inside the Artist Palette Seal. You will be ready to continue painting up to weeks later when you store your paints in a patented Masterson storage container. Dimensions: 16" x 12" x 1-3/4"
