If the purpose is to have a non-messy tinder source at hand..e.g. in a wallet or psk, and you don't like the vaseline-cotton options (though I personally like the vas-cotton option hands down!) I've had good luck with alcohol prep pads (e.g for cleaning an injection site, or pre-stick blood sugar testing).

They're sealed in foil, you can buy them in most Walgreens or similary stores, and I've consistently been able to get them to catch a spark and ignite well. Be sure you get the ALCOHOL prep pad. There are other kinds which won't work.
