Forget about nails, screws and tacks, Command™ Slate Spring Clips are fast and easy to hang! The revolutionary Command™ Clear Adhesive Strip sticks to many surfaces, including paint, wood, tile and more. And like all Command Products, they remove cleanly - with no holes, marks, stains or sticky residue. Rehanging them is as easy as applying a Command™ Clear Refill Strip, so you can take down, move and reuse them again and again.
