These look very promising. I have recently experienced the often mentioned problem of wax candles melting in a survival kit (in one instance it gummed up a mini lighter so bad it wouldn't ignite - glad THAT didn't happen in a REAL survival situation) which has me re-thinking including anything with wax in a survival kit. Any idea if these will have similar problems? It appears that simply putting these in a zip loc type baggy will alleviate the problem of the wax getting on the rest of your stuff, but I am also wondering if the melting will diminish the use of these as fire starters?
