Thank you for viewing. This is an endpin for a double bass made by Mitsuke Seiki Kogyo. Length: 30cm, Diameter: Φ12.7mm, Material: Brass. Original price at the time of purchase: 16,800 yen. It was custom-made to fit my instrument, so it's thicker than usual. I used it intensively for about two years, and then I changed instruments, so I haven't used it and it's been stored away for a long time. It shows considerable signs of use, but if anyone would like to use it, please do.
