This is a Zamst knee support with high support strength. The size is LL. Retail price: 9,130 yen I bought this when I hurt my knee doing squats, but I tried it on once and it didn't quite fit, so I've been storing it. I'll include photos of the Velcro. It's generally clean. Please check my profile. Please consider this item, understanding that it is a used item that has been worn once.
