Valyrian 2 replacement coils come in a 2-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 Valyrian 2 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.    The FeCrAl UN2 coils feature a honeycombed mesh design, enabling the coil to heat instantly and evenly. UWELL’s wicking material is made up of 100% Organic Cotton Fiber. These attributes combined with the airflow and self-cleaning abilities of the Valyrian 2 family of coils affords them the ability to extend their lifespan over previous coils.
