This is an old Japanese army bag. It's made of leather. There is graffiti on the back. See photo 8. The pen holder on the left side is damaged. See photo 18. The leather is not deteriorated. The metal fittings have rust. The main body is: Approximately 26.5 cm tall. Approximately 18 cm wide. Approximately 7 cm deep. As it is an old item, there are scratches, stains, and repair marks. If you have any concerns, please leave a comment. I have taken many photos. Please, those who know about this, please take a look. I know nothing about the Japanese army. Please specify a delivery time before shipping. If not, it will be shipped with the earliest possible arrival time.
