Amami Sanshin Strings (Chiru), Bachi (Bamboo), and Uma (Bamboo) Set This is a set of strings, bachi, and uma for the Amami sanshin. Set includes: Strings: 4 strings x 1 set (2 female strings) Amami Bachi: x 1 (Made of bamboo) Uma: x 2 (Made of bamboo) Since the female strings break easily, we've included an extra one, making it a set of 4. The uma, when made of bamboo, produces a good sound, but can break depending on how it's handled, so we've included two. The bachi is made of bamboo and is approximately 18cm long. It will wear down with use, but can be sharpened with a knife. ※※※※ ※※※※ ※※※※ ※※※※※ Please consider.
