Zippo employees marked a major
milestone soon after reporting to work the morning of September 3rd, when the
400 millionth windproof lighter rolls off the production line.
Zippo officials predicted the milestone
lighter would be stamped out during a run of Armor lighters, distinguished by a
case about 1.5 times as thick as a standard case, and authenticated by a
distinctive Armor bottom stamp. A commemorative logo, designed for the single
400 millionth lighter only, will be dimensionally deep carved, and the date and
time of production will be engraved on the case.
