Denis Wick Euphonium Mouthpiece SM3M (Medium Shank) GP - Unused Purchased new and stored without ever being used. There may be minor scratches from storage (like polishing marks), but there are no dents on the rim or distortions on the shank tip, so it can be used without any problems. I am selling my accessories because I have sold my euphonium. Thank you very much. m(_ _)m *Medium shank.*
