I bought two of these and "stacked them" between two studs in the bathroom hallway.  The cabinets gave me a place to hang my bead necklaces and other costume jewelry.  I simply affixed a quarter-inch piece of plywood behind the cabinets first, and then put coat-hooks inside the cabinet, but drilled into the wood behind the white plastic cabinet frame.  I painted the cabinet doors to match the surrounding walls, and added a decorative handle.  Now my cheap costume jewelry is well-organized and stored close-enough to the bathroom vanity for me to access it easily as I dress for work.  These cabinets therefore saved me valuable floor space and wall space.  I'm thinking of installing one more in my kitchen, as a potential spice rack.  The inside is bright white molded plastic, so it is really easy to clean!
