The .410 shell kit is inside my PSK which is in a Whitman's Sampler candy tin - just a bit larger than an Altoids tin.

My second fishing kit is in a stainless still pill carrier that I got at CVS. It has a triangluar attachment loop on top and seals with a rubber 'O' ring. Attached to the ring is a flint and a P38 (for opening cans and as a striker for the flint) as well as a lanyard made of 10 feet or so of paracord.
