This is a genuine Zippo Lighter wick used to replace the existing wick in Zippo Lighters. They will ship by envelope to all buyers with a tracking number (look for envelope). Ebay estimates the arrival time, they can take as long as 7 to 10 days depending in some parts of the country. Quantities of 2 or more will go usps first class with 3-5 day delivery.I ship daily often within minutes or hours of purchase. I deliver orders to the Post Office daily, yes even Sunday's or holidays when the post office is closed. That means I do everything I can to get you your purchase as fast as possible.
