UWELL Crown V4 (IV) (.4ohm) Coils - 4 Pack

The Crown 4 coils come in a 4-pack, and feature UWELL’s patented self-cleaning technology which collects excess ejuice in a condensation chamber near the bottom of the coil and vaporizes it. This allows for less frequent cleaning of your Crown 4 Tank. These coils also have UWELL’s patented Pro Flavor Core Optimization System (or Pro-FOCS). Pro-FOCS recycles the air through the coil two times during intake in order to saturate each puff with as much flavor as possible.
