7CSP Trumpet Mouthpiece Bach Purchased on Amazon for around 12,000 yen. I bought it thinking I'd try playing the trumpet for fun, but I only played it about twice and didn't get into it, so I'm selling it. It's been used, so please refrain from purchasing if you are concerned. I will answer questions about the product description to the best of my ability, so please understand. Looking forward to your comments. #Bach #7CSP Trumpet Mouthpiece
