These are sticky‑back hook‑and‑loop fastener strips in white, each measuring 3‑1/2 inches long by about ¾ inch wide, sold in a 4‑pack. They feature a self‑adhesive backing that lets you peel and stick them onto most smooth surfaces — such as painted walls, glass, tile, plastic, metal, and wood — without tools or hardware. Once applied, the durable nylon hook‑and‑loop material provides a reusable fastening solution that can be opened and closed many times, making them great for mounting lightweight items, organizing cables or supplies, securing small objects, or creating removable closures in the home, office, classroom, or craft projects.
