Shilverstein SILVERSTEIN HEXA CARBON BLACK LIGATURE Hexa Black Ligature for Clarinet and Alto Saxophone Retail Price: ¥72,270 I received this from a teacher I studied under. I used it on a B♭ clarinet mouthpiece, but it felt a little large. (I used to use a CRYO4, so I might just be used to that size.) I didn't buy it myself, so I don't know the exact size, but it can be used for alto saxophone and B♭ clarinet. Originally, Silverstein ligatures don't have fixed sizes, and you should be able to adjust the string to fit the mouthpiece. However, it may depend on the mouthpiece you are using, so I cannot take any responsibility if the size doesn't fit. ← I used it on a BD4. If the size doesn't fit, please have it adjusted at a musical instrument store. Returns are not accepted. Also, it has been used, so please understand that it is a used item. ☆This ligature makes a very good sound. Once you use this, you won't be able to use anything else. The sound resonates beautifully. The resonance is completely different from the CRYO4. I highly recommend it. The black color and diamonds sparkle, and it looks quite beautiful in person. I am selling it because I am thinking of making the mechanism a little heavier. ⚠︎︎ I am hesitant to sell it because I really like this ligature. If I can't find a better ligature, I will use it again, so I may cancel the listing suddenly. Therefore, I will not offer any discounts. Thank you.
