These are medium‑sized VELCRO® Brand ONE‑WRAP® nylon straps, each measuring 23 inches long and about 7/8 inch wide, sold in a 3‑pack. They’re made from a durable, reusable hook‑and‑loop fastening material that grips itself without adhesive, clips, or tools — simply wrap the strap around the item you want to secure and press the hook and loop sides together for a tidy hold that won’t slip.
