We were talking about this today and I just wanted to pass onto you guys...if you use a plastic waterproof match case DON'T put a Vaseline soaked cotton ball inside your match case. This will destroy your matches, and they will be useless. I do suggest packing a dry cotton ball in your match case to keep your matches from rattling and as back up tinder.
*if your new to this. Cotton balls when wet does not light well. Vaseline or petroleum jelly acts as the fuel and the cotton as the wick. Works well even when wet.
