Selling to organize my equipment. This is a cello endpin I previously purchased on Mercari. It uses carbon for the core material and brass for the exterior, offering a balance of rich resonance and quick response. I'm decluttering because I have too many endpins. The following is a quote from the product description at the time of purchase: *** The inside is carbon, and the outside is brass. The brass part is thin, and the performance is primarily carbon-focused. It's like mixing white and black paint in a one-to-one ratio, where the black would be too dominant, but instead, it's like adding just a drop of black to the white. It's based on the straightforward and natural characteristics of carbon, with the addition of the good resonance and volume of brass. I think it's quite good. ・Length: Approximately 52cm ・Weight: Approximately 84g ・Diameter Type: 10mm ・Materials: Carbon (inside), Brass (0.2mm thick) (outside) ・Accessories: Tip rubber ・Condition: Used, no issues with use #Cello #Endpin #10mmDiameter
