Note: Before using these coils, they must be primed. Before vaping, the organic cotton around the coil must be completely saturated. Fill the cotton wicks around the coil with a few drops of e-liquid. Fill the tank with liquid and let it stand upright for at least 10 minutes (longer in cooler temperatures). A faster approach to prime it is to draw through the tank a few times without firing.
