FITS ALL ZIPPO WINDPROOF LIGHTERS: Maintain your Zippo Windproof Lighter using Zippo genuine Flints. Flints are something that need to be replaced, approximately every few weeks for an average user.
EASY TO INSTALL: Remove lighter insert from case and slowly remove the flint spring. Remove the remaining piece of flint by gently tapping on a hard surface. Insert a new flint in the brass-colored flint tube, replace the flint spring, & tighten!
