Yamaha metal trombone mouthpiece, in good condition. - Brand: Yamaha - Made in: Japan - Material: Metal - Type: Mouthpiece - Condition: Some soiling Purchased for school lessons and used a few times, then stored. There is some blackening, and according to research, it can be cleaned with silver cleaner, but I am not an expert, so I am selling it as is. The box is damaged. There is a name written on it, which I will erase with a pen. Thank you for looking.
