・ This is an octagonal tube for storing the Hichiriki reed pipe. ・ The material is paulownia wood. ・ Paulownia wood is ideal for storing the reed pipe because it has humidity control, insulation, and insect repellent properties. ・ This is not handmade; it was custom-made by a professional, and is probably not sold anywhere else. ・ This item is for sale while supplies last. ・ All items are the same size, so the photos are the same as those used in previous listings. Thank you for your understanding.
