This is a Japanese Army sword bag for a Japanese sword. I do not know the detailed era, but it was stored with the Japanese Army sword that has already been listed. If you are interested, please consider it. [Protecting the Sword]: Whether storing or carrying, using a sword bag can reduce collisions and wear between swords, keeping the sword in good condition when ready for use again. [Wide Range of Uses]: Suitable for most Japanese samurai swords. It can neatly store and preserve swords such as kendo shinai (bamboo swords), imitation swords, wooden swords, mock swords, and cosplay prop swords and knives.
