The Biohazard symbol has become synonymous with toxic waste, nuclear spillages and loud, shouty heavy metal bands. Now, it can be become synonymous with your cigarette habit.
Manufactured by the Zippo Manufacturing Company, a Zippo Lighter is a refillable, windproof metal lighter that should last as long as you at least.
Its wind-proofing comes from the windscreen within which the flame is sparked and due to the adequate fuel delivery. A familiar clicking is heard when the lid of a Zippo is opened and closed, caused by the spring-toggle lever which keeps the lid closed tightly when the lighter is not in use, starving the flame of oxygen and thus extinguishing it.
