Pomarico B♭ Clarinet Crystal Mouthpiece Jewel Series Emerald Mellow This mouthpiece produces a rich, mellow tone that cannot be achieved with an ebonite mouthpiece. I purchased it three months ago from Yamano Music in Ginza, after trying out several and selecting the one with the best resonance. Crystal is less prone to deterioration, so it can last almost indefinitely if not damaged. Due to infrequent clarinet playing and using different mouthpieces depending on the reed, I've only used this mouthpiece a few times. I'm selling it because I'm switching to a wider tip opening. Tip Opening: 1.02mm Facing Length: 18mm Purchase Price: ¥31,900 (tax included)
