A Tank Fit For A King 👑

UWell is a company known for quality, innovation and attention to detail, and with the Crown IV, UWell solidifies its position as a market leader. The selling point of the Crown IV is the innovative condensation recycling base cup designed to prevent leakage, but the awesomeness does not end there. Crown IV coil heads utilise a threadless plug-pull system which enables quick and easy coil swapping, and deliver excellent flavour due to the dual vertical coil design. Mesh coils are also available for purchase separately. This tank holds up to 6ml of e-liquid with the standard bulb glass (standard 5ml glass also included) and the top cap unscrews with a quarter turn for easy refilling. This tank is intended for direct-lung vaping only, but airflow can be restricted using the adjustable airflow ring at the base of the tank.
