I purchased this about 15 years ago and used it for 5 years. Therefore, it shows signs of use. Recommended for those who want to hit high notes easily or are looking for a shallow mouthpiece! 【Specs】 Inner Diameter: 17.5mm Throat Diameter: 4.0mm Depth: Shallow Retail Price: ¥16,500 (tax included) Since it has been well-used, I will sell it at a low price. There is some shank distortion. *See photos. #horn #Tilz
