Dr. Elbow Elbow Supporter (XL size). This is a large size for arm circumferences of 31-34cm, and I used it for tennis for about a year. I felt it was a bit too big, so I recently replaced it with a size L. Although there is some fuzzing on the Velcro part due to use, there are no scratches or tears, and it is still in good condition for use. * The second half of the photos shows examples of how it's worn. I will clean it and ship it. Thank you. Purpose... Hardball
