This looks like good stuff. If you only have a ferro rod and this stuff, you can still get a fire going if you open the bag.

One thing that concerns me is a bag leaking without my knowledge. If it's like the Wetfire stuff, then it will deteriorate. Even if you don't have a leaky bag, there's a shelf life. Plus, I don't know how long it has been sitting on the store shelf. I wouldn't put these in a BOB. In contrast, PJ cotton balls do not have these issues.
