Designed for first-class mouth-to-lung performance and a long life expectancy. Just like the sub-ohm coils that are used with high-wattage mods, these low-power coils feature a Stainless Steel barrel with multiple e juice wicking ports. For superior flavour, the internal Jem coil-core is enclosed in a thick layer of pure organic cotton. Innokin’s Jem tank is equipped with fully adjustable airflow. With each inhale, a precisely controlled airstream passes through the Jem coil core. This is the secret of the JEM device’s deliciously flavourful mouth-to-lung vape.
