Selmer soprano saxophone mouthpiece, Super Session F. Purchased new from a musical instrument store about two weeks ago for 33,000 yen and used a few times. It has been used for a short period of time and is in beautiful condition with no scratches. The tip opening is F, which is relatively wide, but it's not difficult to play, and I was using it without any particular complaints, but I'm selling it because I've switched to a different mouthpiece. It comes with the original box, pouch, and a no-brand ligature.
