This is a used Yamaha trombone mouthpiece. It's a large shank 48L model, which is easy to handle and I think it's a good model for beginners to control. There is some minor dirt, but I polished it with metal polish, so I don't think it's very noticeable. The list price is close to 10,000 yen, so I think it's a good deal to get a beautiful item at this price.
