This Zippo Classic with Crown Stamp Pocket Lighter's strong metal construction provides incredible durability that is literally guaranteed to last you a lifetime. The World Famous Zippo Lifetime Guarantee: Any Zippo metal product, when returned to our factory will be put in first class condition free of charge, for we have yet to charge a cent for the repair of a Zippo metal product, regardless of age or condition. The finish, however, is not guaranteed. "It works or we fix it for free." A flint striking wheel and refillable lighter fluid ignites a bright, windproof flame suitable for both indoor and outdoor use. The windproof feature is provided by a steel windscreen and adequate fuel delivery. The familiar click heard when the lid of a Zippo is opened and closed is caused by the spring-toggle lever which keeps the lid closed tightly when the lighter is not in use, and allows it to readily pop open when needed. The same great quality you've come to expect from Zippo extends to this durable and reliable American made lighter.
