The Masterson Sta-Wet Super Pro Palette is a patented, multi-purpose palette designed to preserve the freshness of acrylics or watercolors for days, even weeks. It begins with a strong, airtight, plastic tray and lid. Depending on the medium you are using, one piece will be the tray and one piece will be the lid. One piece has a recessed area measuring 14½" × 10" (37 cm × 25 cm). Use this piece on the bottom when you are painting with acrylics. The other piece has multiple wells and mixing areas. Use this piece on the bottom when you are painting with watercolors.

For acrylics, use the patented sponge insert and special permeable palette paper (both included). Together they provide acrylic paints with a constant source of moisture. Simply moisten the sponge and lay it inside the tray, then place the palette paper on top. When the lid is open, your paints will have an extended open time. When the lid is snapped shut, the Super Pro Palette will maintain a moist atmosphere that preserves acrylic paints amazingly well. (For best results, use only Sta-Wet brand palette paper, which is permeable, cleanable, and reusable.)

For watercolors, simply remove the paper and sponge.

Made in the USA of tough yet lightweight plastic, the Masterson Sta-Wet Super Pro Palette measures 1¾"H × 15½"W × 11½"D overall.

It comes with five Sta-Wet palette paper sheets and one sponge insert. Replacement sheets and sponge inserts are also sold separately.
