Giant sized art tray for use on a desk, on the floor - inside or out. Made from clear polycarbonate giving it incredible strength and longevity in the classroom where its rigidity means that even when filled with water it can be lifted and moved around without it flexing. In addition to its everyday uses with a variety of liquids and textures for general artwork the tray has been cleverly designed to fit over our Small Rectangular Light Panel (540-004). Ages 3+.
