- ̗̀ Please be sure to read the profile ̖́- Practice mouthpiece for trombone and euphonium (large shank) TMPSLL YAMAHA List price: ¥1100 #YAMAHA #Practice mouthpiece for trombone and euphonium (large shank) TMPSLL Used a few times on its own, without attaching to an instrument. Of course, I haven't used it with my lips, etc. There are only scratches on the outer box, and no scratches are visible on the mouthpiece. Please refrain from purchasing if you are sensitive to used items, as it has been stored by a private individual. If you purchase it together with the euphonium pillow I am selling, I will discount it by 100 yen. (I will include it in the same package.)
