This is a sanshin pick (bachi). It's a pick made from water buffalo horn. Purchased from the Sanshin Association about 5 years ago. If I remember correctly, I used it for about a year, then bought a larger pick and stopped using this one, so I'm putting it up for sale. It's a pick made from water buffalo horn. It features a natural pattern that stands out more than black water buffalo horn, making it unique. The size appears to be L size, based on the length measurement. *Please refer to the photos.
