This is a mouthpiece from BARI. For alto saxophone. I tried it in the store and kept it as a spare, but I'm selling it because I never use it. It's almost new, only tried out, so the exterior, as well as the rails and the inside, are very clean. Tip opening is 1.83mm (about the same as an Otto Link 6). Round chamber. As you can see, it's a mouthpiece that combines the best of rubber and metal. The ligature is included as a bonus. It was sold for 20,000 yen at Sound House, so this is the price.
