Product Name: RELAXEE Knee Support This is a knee support purchased on Amazon. It is a set of two, size M. After purchase, my knee pain improved quickly, so I rarely used them and stored them at home. There are no noticeable scratches or stains, and I think the condition is good. Please refrain from purchasing if you are concerned about minor details, as this is a used item stored at home. Please feel free to comment if you have any questions.
