Tinder-Quik is fire tinder that is completely waterproof and burns for 2-3 minutes. It will help you start any fire.
These tinders don't match the photo and don't break down as easily with your nails. I sliced through one with my knife and kinda flattened it out, but it's still dense, not fluffy. I haven't tried yet, but wondering how difficult it will be to light with a ferro rod. Lit fine with a match.
