BUFFET CRAMPON Bass Clarinet Mouthpiece This is the mouthpiece, ligature, and cap that came with the purchase of a Buffet Crampon Tosca bass clarinet. Although not mentioned in the product name, the ligature and cap are also included. I took them out of the bag once to take photos, but they are new and unused. They have never been used, but the bag is partially torn. Please feel free to ask any questions via message.
