I have owned and used over a 1/2 dozen fire wallets. Just bought "The Fire Wallet 2.0" (truly cool).
Two things should be known about Mark's version. 1st, it comes out of your pocket pre-lit! Sort of
like a pilot light. Opening it without the tell tale strike noise ignites a truly large flame. This
is a huge plus. 2nd, it uses the striker from a "Clipper" style lighter. Works every time. Easy
flint change. As for the thin construction, I see that as a plus(more pocket space). Igniting before
you pull it out is not for the timid and should be rehearsed well before you do this for the TSA guy
at the airport.
