Obviously, we would use whatever we could find when we needed it to start a fire. I was looking for ideas on things which are not normally thought of as fire starters and the dual use nature of some make them better. The lip balms are generally available world wide and can be carried without raising an eyebrow (no fire hazard). I have only tested the white petroleum jelly before. The other lip balms are a great addition. If you don't have it with you when you need it, it doesn't help, and lip balms can be carried in your pocket all the time; small, dual use and effective.
