I purchased this last week. I am selling it because I ordered the wrong model. There are no dents on the shank. This is a mouthpiece supervised by M. Becke, a trombone master. With a large cup and bore, and a thick, sturdy rim, it produces a rich sound. Large shank, silver-plated. 6-1/2M 25.40mm 7.50mm 6.55mm ML Retail price: 15,000 yen ---- The seller states, "I purchased this around 2022 and used it for a while. There is a general feeling of use." ◆Please read the profile carefully and purchase only if you agree to the terms.
