ATAN's free-size supporter that firmly supports the wrist. I am selling this because I accidentally purchased the wrong size (1,840 yen). It is new, but does not have the outer box. Please refer to the actual product photos. You know, you sometimes get pain in your thumb from overuse of your hands, such as tenosynovitis from holding a baby, sprains and fractures during sports, or tenosynovitis from long hours of computer work. But it's difficult to live without using your hands just because they hurt. This wrist belt gently solves those problems! The tip is ring-shaped, making it easy to put on by hooking it on your finger. It can promote early recovery from symptoms of chronic and acute wrist injuries, protect the wrist, and minimize the risk of injury. Size XL Wrist circumference (19-21cm) Material Nylon, etc. Color Black - (Left)
