The Uwell Crown 4 Tank is an upgrade from the very popular Crown 3 Tank.
Made with stainless steel 7 pyrex glass, the Crown 4 looks great & is durable. With a bubble pyrex glass in the package, the tank has a 6ml e-liquid capacity or 5ml with the normal glass.
The ultimate feature of the Uwell Crown 4 tank is the advanced patented self-cleaning technology, the Uwell Crown 4 can absorb the e-liquid in the condensation holder through regular usage and vaporize it. With the top filling design and bottom adjustable airflow this tank is easier to refill with great smooth airflow.
