Wooden Black Painted 12" x 12" Shadow Box. Black/Glass Display Box This was made for displaying fossils, and it's good for that, or for anything else with some depth that you want to show off on the wall or on a tabletop. The black-painted wood box is 12" x 12" x 2-1/2" deep (10-3/4" x 1-3/8" Inside Dimensions) box with a 3/4" frame surrounding a glass front. It has (2) sawtooth hangers in back, and (8) plastic turn-clamps holding in the 1/16" thick black backing. Subtract the frame width for the actual glass size. Add little felt or rubber feet to use it as a table display.
