Selmer S90 180 mouthpiece. I'm selling it because I'm buying a new mouthpiece. This is one of the 30 I chose from. It's usually priced at 46,860 yen, but I'm selling it for 19,500 yen. It has good intonation and response. Compared to the S80 series, the air flows in relatively straight, giving the impression of carrying sound. This mouthpiece can be used in brass bands and chamber music. Regarding the condition of the product, there are some teeth marks and ligature marks, but there are no problems with playing.
