Tired of things sliding around or needing a temporary hold? These self-adhesive hook and loop dots (like super strong Velcro circles) are incredibly handy. You get a huge pack of 450 pieces total, which is 225 pairs. Each dot is about 0.59 inches (15mm) in diameter. One side has the rough ‘hook’ material, the other has the soft ‘loop’—they’re already attached to a super strong, waterproof sticky backing. To use: clean and dry both surfaces you want to stick together. Peel off the backing from the HOOK side and press it firmly onto one surface. Wait about 5 minutes for the adhesive to set a bit. Then peel the LOOP side and stick it to the other surface, wait another 5 minutes, then press them together. They hold really well! The adhesive reaches its full strength after about 24 hours. Great for organizing stuff without permanent damage: stick posters to walls, secure cables under a desk, attach small decor to tiles or glass, organize tools in a workshop, or use in a classroom for charts. Note: They don’t stick well to very fuzzy fabrics, and prolonged sun exposure can weaken them. Also, they’re small parts, so keep away from little kids. A super versatile, reusable (the dots themselves can be pulled apart and re-stuck many times) organizing solution for pretty much anywhere.
