Whether you are expecting zombies or are just the prepared type, it isn't a bad idea to have a set of good matches. For the most part, they won't let you down in an emergency, they don't need butane or a flint.
This particular set of matches, by ProForce Equipment, is wind and waterproof. They are NATO approved and will burn for about 12 seconds, even in strong wind and rain. Get your wallet or purse out, only $4.75 for 25 matches that will never fail you.
