This is a decorative koto from over 40 years ago. Approximately 43cm long. It produces sound when the strings are plucked. Old ones have elaborate decorations and are of good quality. It has 13 strings, but only 10 koto bridges, so 3 are missing. There is also overall aging. This is a junk item, so please consider this before purchasing. It's an easy size to display, so it's recommended for those who want to use it as interior decoration. We offer combined shipping discounts for multiple purchases.
