The Uwell Crown 4 Tank is the latest subohm tank from the Crown Tank series. Introducing a patented self-cleaning technology, the Crown 4 Tank atomizers can absorb the e-liquid in the condensation holder through regular usage and vaporizer it, reducing juice leakage and manual cleaning. The Uwell Crown 4 Tank is designed with a 6ml tank capacity with its pre-installed bulb glass, threaded 90 degree screw off top-fill system, and utilizes exclusive Uwell coils. The Uwell Crown 4 Coils utilizes Stainless Steel 904L (steel commonly used in luxury watches) with results in better flavor and longer lifespan. With Pro-FOCS Flavor Testing Technology, Uwell guarantees the perfect flavor profile for a satisfying vape.
