Distressed Black Floating Wall Shelf, Mantle This listing is for a handmade, all new cedar black wall shelf. This shelf measures about 23 3/4"" long x 5" wide x 3 1/2" tall. This shelf would look great in a bathroom, kitchen, entry, mantle, and more. This shelf is made from fresh Cedarwood. Custom lengths and colors available-just leave me a message with the size and color you'd like. I will then send you a offer. I, the builder, come from a chemically-sensitive family, and hence, do not use any harmful chemicals-just interior latex wall paint, plaster, and acrylic craft paint. MOUNTING INSTRUCTIONS: Screw the strip of wood to the wall. Then, remove the screws in the edge of the board. put the shelf over the strip and drive the same screws you removed thru the top into the strip.
