Thank you for viewing. I used it about twice after purchasing. The following is a reprint from the website. The main effect of wrist wraps is to protect the wrist. When handling heavy weights that tend to strain the wrist, fixing the wrist with wrist wraps reduces the burden on the wrist, which helps prevent wrist injuries. In addition, fixing the wrist allows you to maintain balance and reduces the use of unnecessary force, making it easier to exert power. They are effective as an alternative to elastic tape or bandages. ■Size: W8 x L46cm ■Color: Black ■Material: Polyester, Cotton, Polyurethane
