This is a Yanagisawa soprano saxophone mouthpiece, model SC120. The opening is 1.20mm. - Brand: Yanagisawa - Material: Plastic - Accessories: Ligature and cap This is a soprano mouthpiece I used to own. I will include a ligature and cap of an unknown maker. I am selling this because I am now using a Selmer Concept and a Yani mouthpiece. There are bite marks, but I don't feel any significant dents. Please consider this with the above in mind. Thank you for looking.
