Save paint, time and money using the Masterson Palette Seal. This airtight container safely holds any type of paint palette between sessions. 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. **Please note that a palette is not included in the Artist Palette Seal** Made in the USA of durable yet lightweight injection molded plastic. Measures 1¾"H × 16"W × 12"D (4.5 cm × 40 cm × 30 cm).
