Tinderboxes, of course. <img src="/images/graemlins/wink.gif" alt="" />

If you want something a little lighter, lots of folks use candy tins (with the paint burned off) to both make and store char cloth. Use one without the hole to store it to keep it dryer.

Char cloth works very well, but some folks consider it almost cheating. You can make good char from some fungus, or from punk wood as well. The problem with them is that they only support the technique of striking sparks into the char, not the holding style you use with char cloth to light a pipe... which is also a lot faster, once you get the hang of it.
