Two cello endpins made by Vc yoyo (Mitsuke Seiki Kogyo). One is carbon fiber, and the other, I've forgotten, but I believe it's brass with titanium. My impression after using them is that the pitch becomes stable, and it's easier on the right hand. Length: Approximately 50cm Diameter: 10mm I've used them for a long time, so there's some dirt, but there's no problem with their use. I will not sell them separately. I will pack them carefully and ship them. Free shipping. #cello #endpin
