Kitahara Seikado. This is a shakuhachi flute with the "Seika" mark engraved on it. It is approximately 55cm long, so I believe it is one shaku eight sun. I have not checked if it produces sound. The connection parts feel a bit loose, but it seems to secure firmly when turned. This is being sold as-is. The items in the photos are all that are included, so please check them carefully and purchase only if you are satisfied.
