where would you go to buy black strike on box matches? Answered

Color your own!?!? I checked they make yellow and white. that is because of the chemicals.

The 'Black Strike' on a matchbox/matchbook is nothing more than very fine sandpaper or carborundum (sp?). It creates friction for the match head to reach ignition and set the next flammable material ablaze.

I would first try the supermarket. If that fails I would then try Google.
