This is a Gottsu Sepia Tone #5 hard rubber mouthpiece for alto saxophone. I'm selling it because I've moved to a higher number. It's in very good condition as it wasn't used often. I think it's easy to play and handle, even for beginners. While sound quality is a matter of preference, I personally thought it sounded very good. It comes with the original mouthpiece pouch (drawstring bag) and box. It has been cleaned.
