Crown 4 Tank

The Crown 4 Tank by UWell has incorporated all the best components of the previous Crown Tanks into one crowning achievement

Option (required)

The Crown 4 Tank by UWell has incorporated all the best components of the previous Crown Tanks into one crowning achievement. The Crown 4 comes featured with a new series of Crown coils, possesses a 6mL e-juice capacity, and has a very pristine look. UWell has enabled their new patented self-cleaning appliance that is built into the atomizer core of the new Crown coils. The element is fixed with a compression keeper to absorb surplus e-juice quicker to be used later, resulting in less e-juice being wasted. The Crown 4 employs the pro-FOCS (Professional Flavor Optimization Core System) for better flavor and cloud production. This system works by recycling the in-taken air twice through the core of the atomizer to saturate the recycled draw with additional flavor from the e-juice that is vaporized. The Crown 4 features a beautiful sleek design with knurling at the top and bottom ends that makes unscrewing off the top fill systems easier. This is a powerful, beautiful vape tank that you'll love.
