Thank you for viewing. This is a shakuhachi flute, 45.5cm in length, with six holes on the front and one on the back. There is no maker's mark visible. The fourth photo shows the inside of the flute from the bottom, where the nodes are visible. As I am an amateur, I do not know whether it is a "ji-nashi" (unfilled bore) or not. Please refrain from purchasing if you are sensitive to used items. No claims or returns are accepted after purchase.
