I can carry them anywhere...
That is the great part about them being solid. The worst that they can do is give your pocket and or it's contents a light coating of paraffin dust, they need no container. The size is roughly 1.75 x 2.75 x 1.5 inches. You can light the whole thing to get alot of flame, or cut it into sections if your tinder is drier. And they are very light, almost negligible.
I have a couple in my basic kit, and liberally throught my gear.
If you want, send me an email, and I will send you a couple, last time I made them I made a couple hundred, so I have a few I could send you if you like.
Or, you can make things like this out of recycled materials. Take excess candle max, melt it in a double boiler or non-stick pan. Soak cardboard in the paraffin allow to cool and solidify. Firestarter. Same with folded up newspaper. If you want to have it self lighting, put strike anywhere matches in the corrugations of the cardboard. Or, take paper egg cartons, put dryer lint in the pockets, pour melted paraffin over until saturated but then they don't light as well, leave some lint without paraffin and they light easier. Basically, the paraffin is the fuel and the paper/cardboard is the wick.
I made all of those, and have tons left over, but of all of them I prefer the paper towel/paraffin firestater. Neat, easy, effective.
