Sounds very sketchy, right? No worries, these are empty and clean! Or at least empty! This thin tin case is meant to store a soldier's decontamination items in case the mustard gas - or anything the Serbs were using - gets a bit too close. The contents of this case are either used or discarded as they are expired.
We haven't seen a wide variety of Croatian surplus but what little we've encountered is a bit cheap, and so is this box. Don't worry too much though, it works just as it should; provides splashproof safety for anything kept inside, and is quite fast to operate. The tin opens up with a lively (the experience might vary from box to box) metal latch, revealing the rubber sealing under the lid and the golden-colored insides of the case.
Inside measurements about 9 x 13 x 4 cm, outside dimensions a few millimetres more. Weight 160 grams. Pretty good size for gold teeth, rings or any other little valuables.
What a Croatian decontamination box holds inside, we have no clue, except on the contents list there's something called "TAMPONI", apparently 4 pieces.
Possibly used, likely stored inside the soldier's gas mask bags, until returned to the stores and the contents discarded. We probably wouldn't recommend this for a lunch box role or anything, but any non-edibles it will keep dry and intact.
