Yep. But they aren't just for me, and I've got a lead on some bottles that a bit smaller. They'll work better for some of the guys I'm talking with who are looking for these pre-deployment. I've also been able to find some teflon disks that should be a little larger than the mouths of the bottles, so they will work as seals.

I need about 50 sets total. For 40 buck I can get these guys, and if they don't work, so be it. I can find use for 100 small glass vials. Premixed magnesium and aluminum flake, with a little bit of black powder for ignition, anyone? Pour out a quarter's worth of that, and add some sparks, should light about any tinder I can think of, rain or shine. :P
