20-21 Model UNION FORCE L Size (Manufacturer Recommended: 28.0~30.0cm) I don't remember the exact number of times I used them. I had them on a powder board, so I didn't use them frequently as they weren't my main bindings. I think I used them maybe 10-15 times at most. There are no noticeable scratches, and I think they are in good condition. There are no problems at all. You can still use them for a long time. I think they are in good condition, but they are used sporting goods. Thank you for your understanding. Shipping is via Mercari delivery, and it's free.
