Yamaha cornet mouthpiece. Custom 16E rim is gold-plated. Currently discontinued, and new ones are unavailable for purchase. With a larger size, deep cup, and thin rim, it allows for a more cornet-like tone and intricate passages. Purchased quite a while ago, and not used frequently, but there are multiple small scratches on the rim. (See photos) *No box (item only) Please understand that this is a used item. I would like to sell it to someone who wants it, so price negotiations are possible. Feel free to comment. #Cornet #Mouthpiece #Yamaha #Custom #16E
