The magiccafe link posted above gives a name to contact if you want to buy them made up. It also says that it's really just easier to make them yourself, and to be honest it does look that way to me. I mean, I'm not good at DIY or anything, but putting a bit of copydex on a match and sprinkling some powder on it doesn't seem too hard to me.
By the way, to tie in with the Oz Deposit routine, there's a
fire card to wallet available...more money, more money! It would tie in nicely with the fire theme, wouldn't it (you access your account through fire, you cash the marker through fire!)
