I am selling this item because I used it for a C tuba for a while, but I will not be using it anymore. There are some scratches and shank insertion marks from use, but there is no noticeable damage such as shank dents, dings, or discoloration. There is no box. [From the seller's catalog] ・30H *For B.C tubas. The most popular model. With a typical Helberg-style V-cup mouthpiece, you can get a very soft, dark, and resonant sound. It is especially compatible with instruments with front pistons, and its organ-like sound that gently and broadly envelops orchestras and bands has gained a lot of support. Rim inner diameter 32.9mm Throat 8.0mm Cup Typical deep V-cup Universal shank
