This is a JK Orchestra Series 28H (Helleberg type) mouthpiece. I purchased it last summer and used it once in a concert, but I'm selling it because I bought a replacement. There are some scratches on the shank from inserting it into the instrument, but it's in very good condition overall. 【Universal Shank】 ・28H (Helleberg type) Outer Rim Diameter: 47.2mm Inner Rim Diameter: 32.5mm Bore Size: 8.0mm New Standard Price: ¥24,200 (tax included) Accessories are also included, but the box and sticker have some tears and bends. (The brush is unused.) Please be aware of this.
