Trombone, Euphonium Large Shank Mouthpiece Bach 4G Rim Size: 26.0mm This mouthpiece was included when I purchased the instrument, but I haven't had much opportunity to use it, so there are no noticeable major scratches. There are some minor scratches on the shank. It's difficult to see in the photos, but there are some marks like scratches inside the cup and on the rim. These were present when I purchased it new. Currently, a new one costs about 15,000 yen. It will be shipped in the included case. It's in relatively clean condition, but please understand that it is a used item.
