This hybrid mouthpiece top, inspired by a certain musician's mouthpiece, combines a Bach rim with a 1C cup.
 As shown in the second cross-section diagram, it has been hollowed out in a vase-like shape.


 Each number + C (e.g., 5 + C = 5C) retains the rim feel while producing an even richer sound, and the feedback from several players was overwhelmingly positive.


 It offers a softer feel than metal, making it suitable for outdoor performances.


 The material used is an expensive resin that complies with ISO 10993 standards regarding biotoxicity, irritation, and allergic sensitization.
