I am also listing the same item on other flea market apps. Please be aware that your order may be canceled depending on the timing of your purchase (first-come, first-served). Thank you for your understanding. These are knee supports, both size XL. They haven't been used much, so they are relatively clean. I only have one box left. The instruction manual is inside the box. If you'd like to try them out before buying new ones, which are expensive, how about these? I will not sell them separately. Please refrain from purchasing if you are overly concerned about the condition of used items. Please also check my profile before purchasing.
