The Enhanced Insert is the ultimate upgrade on your Standard Insert, designed to fit all of our standard size classics-styled lighters. It comes equipped with a lid that not only insulates the wick, preventing lighter fluid evaporation, but also auto-opens with the flick of the flint.  Furthermore, the rubber-sealed fill valve at the bottom of the insert provides an additional barrier against fluid loss, ensuring your lighter stays filled longer. The insert's body features a textured design that not only looks great but also protects against scratches and wear, maintaining a pristine look for longer. *Note: Only compatible with our standard size classic-styled lighters. Not compatible with larger classic-styled lighters, i.e. Constantine's Lighter, Jumbo Lighter.
