Your best bet would be to look around (any number of Dollar stores) and find the compressed sponges that they all seem to carry or pick up a freebe (it's an election year, I've seen them handed out as promo's) or three and use those <img src="/images/graemlins/wink.gif" alt="" />. They'll take up a lot less room in your kit and they're clean & sterile (?) when you get them. If you ever need to use them, repackaging isn't your most important issue, and when you get back to a "normal" situation, you can replace them with new ones <img src="/images/graemlins/shocked.gif" alt="" /> <img src="/images/graemlins/grin.gif" alt="" />.
Just my two cents worth.
