I have found these useful to hang my keys on. I stuck them inside a cabinet. They're a good size for key chains. Be sure you leave enough room for the keys to dangle, which I didn't. But, I still find the hooks useful even though I didn't do a good job with locating them. It's not a smooth or sleep or attractive hook, but I didn't need it to be. If you're looking for aesthetics, Command makes nice hooks to display for key rings. [This review was collected as part of a promotion.]
