I didn't expect this shelf to be perfect cause it was on clearance, but it is heavily damaged.  A chunk is missing from the thickness of the shelf where it attaches to the wall.  Also this is made from a very thin piece of board for the top and bottom and attached by center thickness (which appears to be pressed cardboard). On my shelf the top and bottom pieces have separated from the thickness.  I'm going to have to do a creative gluing job. Very disappointed.
