Retail price: ¥56,100 Cup inner diameter: 16.5 This model can be used not only for brass band but also for pops, piccolo trumpet, and jazz. The depth feels similar to a Bach E cup. The size feels like a Schilke 13, or perhaps even more compact. It's been lightened, and it gives the impression that the instrument sounds just by blowing lightly. Please contact me if you would like to see any other areas in detail. I will add photos. Lightly cleaned. #Schilke #Bach #PiccoloTrumpet #Jazz
