These are all made out of plywood, faced with lauan, and have strips of 1x3 for the decorative strips across them. They have sheets of textured frosted plastic as their faces. The boxes have removable backs, and the bottoms are notched for the lighting power cords. All of the facing was painstakingly stained.
These were used as back pieces for a concert, and they were incredibly INCREDIBLY heavy. Approximate cost is for a single box.
