Elbow support made of breathable material with adjustable compression. - Brand: ZAMST - Type: Elbow support - Material: Breathable material - Features: Adjustable compression - Application: Easy to apply - Size adjustment: Adjustable fit Purchased in late January 2026 (Reiwa 8). The seller bought this item, but it was the wrong size and did not reach their elbow, so they never used it. However, they did try it on their arm once. I purchased it from them, but it didn't fit me either, so I have never used it. It's a size M, so the arm circumference 12cm above the elbow should be 22-25cm. This is likely suitable for children or women. The box is not included. It will be sent in simple packaging. Thank you for looking.
