Now in stock! Full Circle, Zippo’s 2015 Collectible of the Year. Zippo owner George Duke personally selected this design created by his son Grant, fourth-generation member of the Zippo family. The design is an outstanding example of the philosophy behind every Zippo lighter - the infinite repetition of an engraved never-ending spiral represents the reusable nature of the product as well as the passing of the flame from generation to generation in the Zippo family.
