●Authentic bamboo tube Dimensions/External dimensions W5.7cm x H16cm x D8cm Inner dimensions Inner diameter 3.9-4.0cm Inner depth 14cm Material: Hinoki from Kochi Prefecture Painting/ink + astringent ink dyeing, linseed oil finish This koto tube is carved from a hinoki square wood from Kochi Prefecture, and the tube and bottom are not joined, making it exactly one piece of wood. It was coated with a moderate amount of ink and astringent ink dye, and finished with linseed oil. This koji cylinder has a gentle scent of cypress. We believe that if you clean it by applying linseed oil about once every six months, it will deepen its depth and make it durable and can be used for a long time. *Shibuboku is a natural paint made from persimmon tannin and pine smoke ink, and is used to dye the black walls and pillars of old folk houses and samurai residences.
