UWell Crown IV 4 Pack of Coils are made out of high-quality stainless steel and are wicked with 100% Organic Cotton. With brand new patented technology the Uwell Crown IV Coils self cleans by absorbing excess e-liquid, for later vapor use, into a condensation holder, which allows for less cleaning of the tank and reduces wasted e-liquid. Another new feature is the Pro Flavor Core Optimization System (Pro-FOCS), which occurs inside the atomizers. It purpose is to recycle the in-take air through the core atomizer to add additional flavor to the e-juice.
*These coils are specifically designed for the UWell Crown 4 Sub-Ohm Tank and will not fit other UWell tanks. Please Ensure your device is capable of firing coils designed with Stainless Steel wire before using these coils.
