Lotus mouthpiece, a second-generation model that is no longer in production. This is the bronze model, known for its warm tone. The inside of the cup has a satin finish, which is characteristic of that era. This is the HC type, which has a throat size 0.2mm smaller than the standard model. It's perfect for those who find that they take in too much air when trying a Lotus! I bought it new six months ago, and since I haven't played it much, there aren't many shank scratches! Thank you.
