The Daler-Rowney Stay-Wet Palette is a simple but effective idea: it keeps your acrylic paints moist and useable for weeks, reducing waste. You simply soak the sheet of reservoir paper at the bottom of the palette with clean water, and dampen the greaseproof paper above it. Then get painting, using the greaseproof sheet just as you would any other palette. When you’re finished for the day, close the clear lid, and the paint is kept moist by a simple process of osmosis that draws water up from the reservoir as it’s needed. This small Daler-Rowney Stay-Wet Palette measures 254mm x 279mm x 25mm and comes with three sheets of reservoir paper and 12 sheets of greaseproof membrane paper (replacements are available separately).
