Trombone/Euphonium Mouthpiece JK4G (Large Shank) Unused I purchased this new and have kept it in storage without ever using it. There may be some minor scratches from storage (just 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'm selling my equipment because I've gotten rid of my euphonium. Thank you. m(_ _)m
