This is a ligature for soprano saxophone and B♭ clarinet. I purchased it from Shimamura Music last year and tried it once. It has a very light and airy feel, and the sound is clear. No box. It will be delivered in simple packaging. The current list price is 10,000 yen. The following is a description excerpted from the website. Please refer to it. ************** A unique ligature design using "Leafleck" that allows the reed to vibrate freely, achieving a rich sound and volume. The unique design minimizes the contact surface between the reed, mouthpiece, and ligature, enhancing sound conductivity and allowing the reed to vibrate as freely as possible. It features a light playing feel and rich overtones. The response is also fast, and it is excellent for staccato playing. It can flexibly accommodate differences in mouthpiece diameters and materials (rubber, metal, etc.) depending on the manufacturer.
