My name is David and I am the owner of D&R Woodworks. This is a wooden blocks and tray set. The blocks are made from 2x4s ripped on the table saw to various sizes. The blocks are dyed with food coloring and finished with a shellac and orange oil/wax finish. The tray is made from 3/4 plywood and a thin plywood base. It was assembled and then painted white an finished with shellac.
