CW-X arm covers. I recently purchased a size S, but it felt too tight the moment I put it on, so I listed it on Mercari. I love CW-X's spats and innerwear, so I thought I'd try the arm sleeves too! However, the size didn't fit... I repurchased a size M. While it doesn't feel as tight as the S, I'd prefer a little more room. I'm selling these with a heavy heart. The retail price for both arms is about 8,000 yen. I bought four, so it's 16,000 yen. So sad. Thank you for your consideration. ↓ [Material] 70% nylon, 30% polyurethane M size (Maximum upper arm circumference: 26-29cm) CW-X's unique taping principle links the muscles of the entire arm, reducing unnecessary movement during activity, thereby reducing stress on the elbow. - Brand: CW-X - Color: Black - Size: M - Type: Arm supporter Thank you for viewing.
