I have for sale my own Sakshama G MB tenor saxophone mouthpiece in .112 tip opening, CNC machined in white delrin with my precise facing work. I started doing my own CNC machined mouthpieces just recently. Delrin is a very hard plastic with high tensile strength and impact resistance so it can be machined to metal dimensions without the need to make it bulkier like rubber or other plastics. It plays like my hand finished mouthpieces and I give my full satisfaction warranty. Will ship worldwide from NYC.
