Selmer, Claude Delangle mouthpiece. The listing may be cancelled. Please be aware of this beforehand. Please read the profile before purchasing. This is a used item, so please refrain from purchasing if you are sensitive to such things. Returns and refunds are not accepted after purchase. I purchased this here previously. The previous owner seems to have selected and purchased it from over 10 mouthpieces at a musical instrument store in Tokyo. Compared to other mouthpieces, it allows for sharp sound initiation and articulation, and is very easy to play. The "Delangle" lettering is slightly darkened. This mouthpiece has resonance and a good tone. Including the previous owner, it was used for about a month. Please feel free to comment if you have any questions or would like to discuss the price.
