Yamaha Short Cornet Mouthpiece 11E4 (Silver), box not included. This is a new item with a suggested retail price of 6,380 yen (tax included). Rim inner diameter: 16.46mm, Throat diameter: 4.20mm It has a deep V-shaped cup for good airflow, and is a standard mouthpiece for British style. I tried it a few times, but it didn't suit me, so I'm selling it. There are small scratches on the rim and slight shank marks, but there is no damage that would interfere with playing. Please understand that this is a used item before making a purchase. Also, please note that we do not accept price negotiations.
