For about a year now I've been using an empty chapstick container as a PCB straw. I fill it with lint from my massage linens (100% cotton), sometimes mixed with fatwood dust/chunks and birchbark. I scoop out the last of the chapstick and use it to seal the end of the lint (hence the comparison with PCB's). I've put them through the washer multiple times with no negative results. They are unobtrusive, and MUCH easier to operate than PCB straws as you pull off/bite off (in last ditch efforts) the lid and turn out the material and light. In an last ditch effort you can even light it without screwing out the whole core, and it lights like a candle, however this burns the plastic as well. Mine have stayed lit for 3+ minutes, and are very effective at starting fires with moist materials- as my brother and I found out while hunting last fall. I've sent out a few with giveaways here but have not heard back if they were used. You can also use Vics rub instead of chapstick and it can help with congestion/sinus problems along with other uses of chapstick.
