Soft velvet lines the interior, which is the detail that keeps polished silver and plated pieces from scratching against bare board - most cabinets at this size leave the MDF exposed. It mounts on a wall or hangs on a door, and the hanging height is adjustable, with a spare screw bag supplied for either method. The mirror measures 43.5 x 10.5 in on a frame 14.5 in wide, 3.5 in deep and 56.5 in tall. Fifteen LED lights run on three AAA batteries, not included. Real glass mirror over quality MDF.
