Elastic Elbow Support Sleeves - Size M

Selling a pair of RAKIIE elbow support sleeves, new, in box, with instruction page included. Arms need to have circumference at least slightly larger than 9.25" above the elbow and 8" below the elbow, otherwise the compression effect won't work... and arms much larger than that would experience too much compression. The sleeves are made of 50% nylon, 35% latex silk, and 15% spandex.
