As an FYI I was messing around with the $1 Coleman's match case from Wal-Mart a few nights ago and was surprised to find that the cheap, tiny fire steel glued to the bottom does indeed work well enough to light a cotton ball with ease! I was actually pretty surprised. Now after scraping it a dozen times to test it I'd say you probably aren't gonna get more than a couple dozen fires out of it at best before it's gone but in a pinch I'm glad to know it works.
