This product is not new, it is used. Insulation, Waterproofing, Cold Protection This belt around the ankle helps to reduce the entry of cold water from the ankles. By tightening it, it prevents the cuffs of wetsuits from rolling up, reducing water from entering through the gaps. Some people can also use it on their wrists. It uses a stretchy material and is easy to adjust the length. There is only one of this product, and it is also sold on other sites, so please forgive us if it sells out. ■Contents: 1 set, 2 pieces plus 1 spare I used a leash cord strap for one foot, and the other three were attached to both wrists and one foot.
