The kits ive seen all have some sort of rod sticking out of the end and a compas on the other, so they can go on a keyring or a lanyard, my suspicion is they will just look like a novelty keyring!

I'm pretty sure i could make something myself for £10 that is exactly what i need, rather than but one though. I have a few different "capsules", mostly i have put some sort of tinder/sure fire and a small candle, having a fire steel on the same keyring.

I have one of these that i still havent decided what to put in it, its alot bigger than you would want on your keyring though!
