Now a magnesium bar with striker, and fishing line, (the line can also be used for snares) and small assortment of hooks, lead sinkers, etc., compass, tweezers magnifying glass combo. That should do it, for a small compartment. Oh, and a tube or two of Carmex lip balm, and or a small bottle of hand sanitizer. Both, will light with a spark, and the carmex will act as wax on small sticks, to get a fire going. Or a couple of small tea light candles. Speaking of which for general info, you can use deodorant, zinc oxide, petroleum jelly, neosporin, etc. to keep a flame burning for a lot longer, so you can get a good fire going, doritos, fritos, cheetos, etc. will burn like a candle, because of all the oil in them.
