Cardboard Water Tray 20.4" x 16.5" x 2.7"Mercurius
A fantastic new idea from Sweden. This cardboard (FSC) water tray has been specially designed to hold water without leaking, even for long periods. Once it has been folded into shape, the tray is the right size to accommodate our most widely-used paper formats (25 x 32.5 and 44 x 32.5 cm). A simple and easy solution for soaking your wet-on-wet paper to achieve amazing painting results. The box comes flat and has simple instructions, so you can easily and effortlessly turn it into a 20.4 x 16.5 x 2.7 inches (52 x 42 x 7 cm) water tray.
