This is a Bach 3C mouthpiece. I purchased it this year and have used it for about a month, so it's in excellent condition with little sign of use. I'm selling it because I preferred the rim gold version. The 3C itself is a very easy-to-play model, but the platinum plating makes the sound quality significantly better! How about taking this opportunity? Original price: 17,000 yen Product Overview: Platinum-plated finish!! Bach mouthpieces are the most widely used by professionals and beginners around the world.
