It's a candy tin, similar to Altoids. Candys are very rarely sold in tins in my country, I've been to some big shops and couldn't find the right tin - and yesterday I accidentally found one on a gas station It's just the right size for the mini-kit - small enough to be carried all the time, large enough to fit all the necessities to supplement my EDC (knife, Leatherman, lighter, flashlight, duct tape, very basic first aid). I'll keep playing with it to see how much I can put inside.
