I need a few suggestions for pre-packing tinder. I do have some requirements. 1. There can't be any possible way it could be mistaken for drugs of any kind. 2. It must remain viable after long storage periods in a car trunk. 3. It can't give off flammable or toxic fumes. 4. It must be easy to ignite with a fire steel. That's about it. I plan to store it in a ZipLoc bag in my hurricane back pack if that makes any difference. It will not be near food or water. Thanks for your suggestions.
