Manufacturer: Nippon Sigmax Product Name: Knee Supporter Short 2 I purchased this after being recommended by a medical institution when I injured my lower knee. I wore it over leggings for a few days, but no longer need it, so I'm offering it to someone who can use it. I believe it cost around 9,000 yen. The size is approximately S to M. Soft bones (offset joints) are inserted on both sides, and the area that touches the back of the knee is mesh. Instruction manual included. Please purchase only if you understand and accept that this is a used item.
