It looks like those zip fizz vials are kinda bulky, how many pills can you fit?

I happened upon aluminum pill fobs at the dollar store ... for a dollar ... real aluminum , like ezy dose (used to be?) ... fits a whole glass bottle of nitroglycerin

I think this kit might be able to fit inside a Nalgene bottle
M40's "ATV" Wilderness Survival Kit .... amazing amount of stuff stuffed in there
