These are Zippo lighters manufactured in August 2001.
Zippo lighters have been an iconic American product since their introduction in 1933. Founded by George G. Blaisdell in Bradford, Pennsylvania, Zippo Manufacturing Company quickly became renowned for its windproof lighter, backed by a lifetime guarantee. The simple yet robust design has remained largely unchanged, making Zippos a favorite among soldiers, smokers, and collectors alike. Zippo lighters are highly collectible, with certain models and designs fetching significant prices. Factors such as the year of manufacture, special editions, and advertising tie-ins can greatly influence their value. The date codes stamped on the bottom of the lighter are crucial for identifying the year and month of production, adding to their appeal for collectors.
