I normally avoid hard cases like the Altoids can because I front carry everything in my pockets so hard cases get in the way of my wallet in one pocket and keys in the other makeing it uncomfortable, but after reading this I decided to see what I could fit into one myself. While I was at the store today, checking out, I reached over and grabed a tin of Altoids and decided to pile together the house, camping, car, and hikeing FAK and pick and choose till I filled the tin. When I got home I dumped the Altoids into a ziplock baggie, gathered the FAKs tore them all apart so I could see what all I had to work with (Anyone else feel like they could stock an emergency room office cabinet with supplies out of what they have in their FAKs?) and proceeded to pack the tin and this is what I have in there presently:

15 - 3.5x0.5in water proof medical tape strips
1 - 3x2in synthetic adhesive backed moleskin
2 - cotton applicators (Q-tips)
1 - medium safty pin
6 - 3in latex free band-aids
5 - 1.5in band-aids
4 - butterfly closures
1 - fingertip band-aid
1 - knuckle band-aid
2 - 2x3in non-adherent pads
1 - single use krazy glue tube
1 - ammonia inhalant
1 - 2 pack 325mg each acetaminophin
1 - 2 pack 200mg each ibuprofen
1 - 2 pack electrolyte replenisher tabs
1 - 2 pack 2mg loperamide HCI (Imodium AD)
1 - 2 pack 25mg diphinhyormine HCI (Benadryl)
2 - 1gram packs antibiotic ointment
1 - sting relief pad
1 - povidone iodine prep pad
2 - alcohol prep pads
1 - packet of sugar

There is a bit of space left in the tin but its not 'useful' space for anything that I had in the other FAK.. I was thinking about tripling the medications and adding a few others (notably asprin, all I had was in bottles) by packageing them from the bottles in Glad Press-N-Seal and labeling them with a ultrafine sharpie, but I don't know how well this protects things from water/humidity/elements.. anybody have any experience with this?

P.S. The Altoids are already all gone, I went over to my extended families house for a family dinner after I got it all together and showed it off 'as an exercise just to see what I could fit in the tin' (I'm a... 'closet preparationist'.. my family still thinks its all about camping/hikeing.. they never seem to question the fact that I always seem to have something for whatever is needed when its needed) and promptly took out the baggie of Altoids and offered them around to everyone, by the end of the night they were all gone.
