Thank you for viewing. This is a Ryuteki (Japanese flute) that has been maintained by a flute maker who is also a musician. It produces a clear tone. It's easy to use for sessions with contemporary music, and its appearance is beautiful, befitting an antique instrument. This is a recommended flute. As it was passed down to me, I do not know the maker or the materials used. Please refrain from purchasing if you are sensitive to used items. No claims or returns are accepted after purchase.
