Surplus Chinese PLA Army Military Box Steel Box Case 6.2x3.4x2.5"
The size:6.2x3.4x2.5 inch
The net weight:394g
The Diaphragm circular hole diameter:1.0 inch
Note:I'm not sure about its purpose at the moment. Some people speculate that it is an ammo box of Flare Gun. But this is just speculation. I hope you can develop its features. Bringing you better use.  I use it as my office pen holder. It looks cool!!!
