Zippo's history dates back to the early 1930s – their lighters have since become one of America’s greatest and most recognizable icons, famous around the world. While the shape has remained mostly unchanged over the decades, there have been countless different designs and finishes, inspiring some to take up collecting the lighters, while many other brands have commissioned their own designs for promotional purposes. Zippo lighters are backed by a lifetime guarantee and it is said that no one has ever spent a cent on the mechanical repair of a Zippo pocket lighter regardless of the lighter’s age or condition.
