This is a genuine Buffet Crampon bass clarinet mouthpiece. I purchased it used and used it as a temporary mouthpiece until I bought a new one. There are many scratches from the ligature, but there are no cracks. It can be played without any problems. There are some teeth marks, so I have attached a Vandoren mouthpiece patch. Please feel free to comment if you have any questions. I also welcome requests for bulk purchases and price negotiations. *Please see my profile for more information.
