The box mine consists of a wooden box with a hinged lid with a slot cut into it. The slot presses down against a retaining pin, which holds back the striker. When sufficient force is applied to the mine, the retaining pin moves, allowing the striker to hit the detonator.

The box mine is commonly used throughout former Warsaw Pact countries. Although it is dangerous because the mine can not be detected by a metal detector, it has a relatively short lifespan, as the wooden box is vulnerable to rotting and splitting, which renders the mine inoperable.
The Box Mine was tested against the M18 Claymore in eliminating a group of three targets. The box mine failed to trigger the pointman's 100G shock patch but still killed it with a potentially fatal leg amputation while the M18 Claymore killed all three targets through its shrapnel spray. The edge was given to the M18 Claymore for its higher lethality.
