This is a Selmer alto saxophone mouthpiece, ligature, and mouthpiece cap set. All are Selmer brand. It was an easy-to-play and user-friendly mouthpiece, even for a beginner like me, so it's sad to part with it. However, I'm selling it because I want to debut a new metal mouthpiece next year. I will disinfect and clean it thoroughly before shipping. Thank you for your consideration.
