Professional knee sleeves. 2XL size. 40.5cm - 43cm Please refer to the size chart in image 7. I purchased these on Mercari, but the size didn't fit. I tried them on once at home, and I could barely squeeze into them, making walking and bending over very difficult. The previous seller also mentioned they were selling them due to a sizing mistake, so they are practically in new condition. However, there might be some minor scratches, so I've listed them as "no noticeable scratches or stains." Please check the images. No pets, non-smoking environment. Thank you for looking.
