Bb/A clarinet mouthpiece This is the Licostini FDC model. This model incorporates metal into the standard type. It was supervised by Fabio du Casola, a professor at the Zurich University of the Arts, and its tip opening is similar to a Vandoren B40 Lyre. I was able to choose this one from among three mouthpieces, which I received directly from Mr. Licostini. I personally use the Licostini RG Ottone model, and this one has been sitting unused for a long time. It has only been test-played. I think it's a really good piece. It's a shame not to use it, so I'd like to offer it to someone who can, but since it's in good condition, I'm afraid I'll have to offer it at the original price I received it for. There is no outer box. I think the Ottone model in particular is quite rare and not often found in stores.
