This is a Crampon mouthpiece that came with the purchase of a bass clarinet. Please note that this is for a bass clarinet. I stored it after trying it out once. It has only been used for trial playing, but it is not new, so there are some minor scratches. Please refrain from purchasing if you are concerned about this. It can be used without any problems, so I would like to give it to someone who needs it. There is no box, so it will be shipped in a Vandoren B40 B♭ clarinet box.
