I have the long one and fit:
-Micro fishing kit (one of IronRaven's from awhile back, in the amber glass vial)
-5 lifeboat matches, striker strip
-2 tinder tabs and a spark-lite
-2 micropur tablets
-needle, thread, 2 safety pins

Things wound up a bit too smooshed for my liking, and a little too hard to get out of it when needed. Then I realized I use it more as just a matchsafe than as a kit, but it's still a good alternative for a tiny kit.
