That's what I have on my key chain. For the price and size they are great. I bought about 10 of them and stuck them on my keychains, in my kits, everywhere. I actually used the one on my keychain to teach firestarting to boy scouts at summmer camp this year. We got 6 nights worth of fires started with it and a little cotten/vasiline, even when it was wet out, with no problem.
