Plastic straight design clarinet mouthpiece. Long facing, with a tip designed slightly wider than the 5RV Lyre. The length of the facing increases flexibility, balancing the core and mellowness of the sound. Breathing is also good, and you can feel a core, heavy sound. Compared to the M15, it creates a moderate resistance. Material: Ebonite Tip Opening: 1.15mm Facing: L Type: Traditional I purchased this here and tried various setups, but it didn't suit me. I'm selling it because I changed my setup. There is some discoloration on the ligature, but it shouldn't affect playing much. When shipping, I will thoroughly disinfect the mouthpiece patch adhesive residue, but it may not be completely removable. Thank you for viewing.
