Uwell - Crown 4 IV Sub-Ohm Tank

Presenting the newest Crown tank from UWELL, the Crown 4 has a self-cleaning feature where excess juice that accumulates in the bottom of the atomizer is pulled back up into the coil to atomize it, resulting in less clean up and more efficient juice utilization. The Crown 4 is made from stainless steel and comes in a variety of colors with a beautiful polished look to catch your eye or to finish that clean mod look. UWELL has further improved their top cap design with the Crown 4, the top cap only needs a 90 degree twist to unlock and refill, making for fast refills and more time vaping. Uwell has hopped on board the mesh coil train, and is ready to add extra flavor to your vape. The Crown 4 comes with two type of glass, the bubble glass which is already installed on the tank and holds 6ml's of juice, while the straight glass holds 5ml's of juice. Also included is replacement o-rings, a drip tip cover and a replacement coil.
