This is a 10mm single-eye endpin. I've used it a few times, but it didn't suit my instrument. It would be perfect for those who use instruments like Oriente. It's almost unused. - Type: Single Eye - Size: 10mm - Product Name: Endpin - [Single Eye] Standard - Retail Price: ¥28,000 (¥30,800 including tax) The shaft diameter is 10mm and the length is 50cm. It was also featured in the stringed instrument magazine "Sarasate." Three Features of the "Single Eye" Endpin: - Made of special stainless steel that has been vacuum-hardened at a slight temperature, so it powerfully supports the instrument. - It ensures an exquisite balance of "power" and "playability." - It brings out the instrument's original potential: the stickiness of the sound, the extension of the reverberation, the richness of the overtones, and the resonance of the instrument. *Compatible with both cello and contrabass.
