I initially purchased the medium bag, with the tin and ferro rod, and quickly fell in love with these awesome fire starters. So much so, that I purchased 2 Bigfoot bags, so that I can give them to family and friends, who I knew would appreciate them. These have quickly become my favorite fire starter, whether it be for the firepit, the camp site, or even the BBQ pit. Keep up the great work, and know that you have a customer for life.
