This sand and water tray is not recycled plastic, but the frame is made from the same marine plywood used in boats and is therefore extremely tough. We designed a plywood version of our recycled plastic one in case your budget is very tight. Can be used both indoors and outdoors. The two trays are, as you might expect, made from very robust plastic. They slide neatly into the frame and are easily removed for cleaning. The recesses at each end of the frame act as handles allowing you to move the product around as necessary.
