I've used a whole pack of these, they're very handy because they're narrow on one end (only 3mm) and have a protective tab on the other so they don't snag or scratch anything. I used Container Store plastic hooks on their steel stand to hold a couple of pots and the handles on the pots caught those hooks and pulled them out when I took one off, even when they were safe. Then I had to find spots where the hooks jumped all over the kitchen floor. Grrrrr. The 3mm width and no protrusion end make them ideal for a non-retractable auxiliary board. I've also used them to replace a missing shower curtain hook, hang a fabric shoe rack from a sturdier rod, replace the included square hangers over the door, and hang a flower pot.
