I picked up a couple of these at a Walmart 50% off sale this past weekend. I have to say they work so well I had to tell you all about them. They come two to a paper envelope package. Kind of look like wax in a plastic pack 2"x4". I touched a match to the corner and it really took off in a flame about 6" high. The directions say they burn for 15 minutes, but I couldn't tell because the small fire took off and covered it up. I think these would be great for getting a fast fire in an emergency or starting some damp kindling. They're made by CSL and are in the same section as the chimney sweeping logs.
