Japanese Mortar Round, FULLY INERT OF COURSE!-Not our specialty so a physical description will hopefully give you a good idea of what we have to offer here. It is 14" long from the bottom fins to the tip of the fuse. It has a yellow stripe around the circumference towards the top. There is Japanese writing in white ink on the body. There is a red stripe at the end where the brass fuse screws in. Someone wrote "INERT" in English on the body as well. A great display piece!
