These are Power Dragon knee sleeves, size M. I purchased them from the Squat Mania website. They have the Power Dragon logo, not the Squat Mania logo. I used them once a week for leg training for about a year. Currently, I mainly use SBD and P.L. College knee sleeves, and I no longer have the opportunity to use these, so I'm putting them up for sale. They are not in perfect condition, but they are in good condition without any scratches or deterioration. Thank you.
