Thank you for viewing. This is a Shinobue flute, 4-hon choshi (key), purchased from a flute maker's workshop. It's an excellent flute with a superb sound, and I highly recommend it. It is being sold as is. Please understand that it has been stored by a private individual, and I would appreciate it if you could assess the condition from the photos. Please note that all sales are final, with no returns or claims.
