lol I actually use a mini-tin as a subkit inside a tobacco tin sized kit, to hold all the little bits and pieces.
It really is like a little match box. I keep a roll of duct tape, my fishing gear, a ferro rod/magnesium rod, an LED light, two curved needles, safety pins, eyelit screws, and tinder quik in there.
Not really stand alone but great for sub compartmentalizing stuff.
