TUBAMANPlus Zero Series (Resin Mouthpiece) This is a resin mouthpiece planned and developed by TUBAMANPlus. *Because it's a hassle, individual sales are not possible. It's white, so there are oil and grease stains, but it doesn't affect playing. Please purchase only if you understand. The price is set on a first-come, first-served basis. It's quality that can be used in a performance (in my opinion). However, I was concerned about what others would think, so I didn't have many opportunities to use it. It's a really good mouthpiece, but if you don't mind what others think, please, please do! The following is quoted from the official website: #328B For B.C.
