Those round Altoids Sours tins...

...makes a good container for a fishing kit. You can buy small spools of fishing monofilament (I used some 12-pound Berkely) that fit inside them, and have some extra room on the spool for wire, string, wire leaders, what-have-you. The spool has three "spokes" which can be cut out to make room for split shot, hooks, jig heads, and so forth.
