Designed specifically for the Masterson Sta-Wet® Painter’s Pal, these premium absorbent sponges ensure proper humidity control by transferring moisture evenly to the Sta-Wet® palette paper above. This helps maintain the ideal environment to keep acrylics and other water-based paints fresh, smooth, and ready to use for days—even between painting sessions. Each sponge fits perfectly inside the Painter’s Pal tray, offering consistent coverage across the entire mixing surface. Durable, reusable, and easy to clean, these sponges resist mold, odor, and breakdown with proper care. Ideal for studios, classrooms, and travel setups, this refill pack helps artists preserve paint quality, reduce waste, and extend palette use time.
