A reed that produces no sound. For practicing instruments at home and for training in diaphragmatic breathing. [New, Unused] - Model: M (for A.Sax) - Brand: Gottsu - Features: Silent Reed Retail Price: 4,400 yen (tax included) Thank you for viewing. I purchased this new, but I am selling it because the size was incorrect. (The first and second images are actual photos of the item) I opened it once without realizing it, but it is unused. Due to amateur storage, there are scratches on the bag. Thank you for your understanding. For alto saxophone.
