Imperial Japanese Navy Aluminum Lunchbox This is a medical kit from the Imperial Japanese Navy. It was previously treated as a lunchbox or a box for personal belongings, but recent research has revealed that it was a medical kit given to the bereaved families of Navy personnel who died in action. Size: Approximately 19cm in length, 14cm in width, and 5.4cm in height. There is a small chip in one place (see photo). As this is an antique item, there are scratches and dents. Please purchase only if you understand that this is a used, antique item. I am also listing other Imperial Japanese Navy goods. Please take a look. Shipping via Yu-Packet Plus.
