Demo Bach 7C trumpet mouthpiece in silver plate. Open-box mouthpiece is in excellent, like-new condition in original Bach plastic. 

A demo item is a new item that was either: (1) designated as a demo due to in-store play testing or display use, or (2) purchased from the manufacturer as demo stock, often because of minor cosmetic imperfections. In both cases, the instrument is new and has not been previously owned or extensively used.
