I am currently cleaning up my parents' house. I believe this is an old item. I have no knowledge of the shinobue (Japanese flute), so I cannot answer any questions. Please purchase this if you know about it. It has a beautiful luster and is very attractive. Also, it has thread wrapped around it. There is no cover. The handkerchief placed underneath is not included in the product. Please refrain from purchasing if you are overly concerned about details. I will not be offering any discounts. The shipping method may be changed. s19
