Euphonium mouthpiece made by Glanz. This is the "NUE" (Nue) signature model by Mr. Kaizuka, one of Japan's leading professional players. The following is an introduction from the seller: This mouthpiece was created from the unique perspective of a euphonium player, with repeated trial and error in the shape and depth of the cup, and the backbore shape, to pursue the tone required for the euphonium. It responds well and provides a stress-free playing feel. This mouthpiece is highly recommended for those who usually use a Bach 5G equivalent. There are no significant scratches or dents, but it is technically a used item. Therefore, there are some scratches and discoloration due to use. Please consider this if you understand this point. Please refrain from purchasing if you are sensitive to this. ＜NUE Specifications＞ Large shank Rim inner diameter: 25.5mm Cup depth: Deep Throat: 7.0mm Finish: Silver plated There is no dedicated case.
