BACH CORP. 6 1/2 AL trombone mouthpiece (small shank). The features of this mouthpiece are as follows, and it is in relatively good condition: ① The model number has a dot. ② There are almost no noticeable scratches or stains. ③ It has the original outer box and plastic bag from when it was purchased. Please refrain from purchasing if you are looking for a perfect item or are very particular, as it has been stored at home for a long time. Thank you.
