This is a 13-string koto. It's a small koto, about 166-167cm long from the dragon head to the dragon tail. There are a few small marks on the soundboard where the koto bridges have fallen over. They do not interfere with setting up the bridges. There are no cracks on the underside or the sides. It's made of paulownia wood. It produces a beautiful tone. A full set of bridges and other accessories are included. How about it for practicing at home for the koto club? The strings are not frayed and are in good condition. You can play it right away. Once it arrives, just set up the bridges and tune it, and you can start playing immediately.
