After suffering many cherries on my thigh from over filled Zippos,I finally learned the appropriate way to fill them. After extracting the working part from the case,simply pull up the felt to expose where you would store extra flints,then fill til the fluid puddles. When reassembled,the felt completely absorb the extra fluid. Wa-lah! No more owies!
Only took me about 5 years to learn that trick.
