Shinobue (Japanese Bamboo Flute) Product Details: This is a shinobue in the key of Doremichō (Do-Re-Mi scale), with 7 holes and a 6-hon chōshi (key). The length is approximately 46cm, and the diameter is about 2cm. It comes with a flute bag. This belonged to my uncle. He bought it about 20 years ago. He says he hardly used it. #Shinobue #Doremicho #6HonChoshi Please purchase only if you understand that this is a used item.
