The Masterson Sta-Wet Painter's Pal Palette is a patented, airtight palette designed for oil and acrylic painters. It preserves the freshness of your paints for many days, saving you from having to clean your palette after every painting session. For acrylics, use the Painter's Pal with Sta-Wet palette paper sheets and a sponge insert (both included). Moisten the sponge and lay it inside the tray, then place the palette paper on top. When the lid is open, your acrylics will have an extended open time. When the lid is snapped shut, the Painter's Pal will maintain a moist atmosphere that preserves acrylic paint amazingly well. (For best results, use only Sta-Wet brand palette paper, which is permeable, cleanable, and reusable.)
For oils, simply remove the sponge insert. You can also substitute a conventional palette paper when using oils. Made in the USA of tough yet lightweight plastic, the Masterson Sta-Wet Painter's Pal Palette measures 1"H × 13"W × 12½"D (2.5 cm × 33 cm × 32 cm). It comes with five Sta-Wet palette paper sheets and one sponge insert. Replacement sheets and sponge inserts are also sold separately.
