This steel strongbox represents the ingenious combination of artistry and engineering resulting in a masterpiece of the Russian Tula workshops.

If the box is locked, the lid will open slightly before triggering a mechanism to reveal two pistols which, if loaded, will then fire on the unwitting intruder.
