・ An octagonal tube for storing the Hichiriki reed pipe. ・ The material is paulownia wood. ・ Paulownia wood has moisture-regulating, insulating, and insect-repelling properties, making it ideal for storing the reed pipe. ・ This is not handmade; it was custom-made by a professional, and is probably not sold anywhere else. ・ This is a limited-stock item. ・ All items are the same size, so the photos from the previous listing are used. Please understand.
