Ensure your Zippo windproof lighter performs at its best with Zippo's genuine wick, packaged securely for freshness. Each package contains one 100mm (4-inch) wick, compatible with all Zippo lighters. To maintain optimal performance, replace the wick when it becomes black from carbon buildup. Simply pull it up with pliers until a clean section is visible, trim it even with the top of the chimney, and straighten it for perfect functionality.
