The Playboy Vixen Mini Tank is the compact version of the Playboy Vixen Tank. While it is smaller in comparison, the performance out of this tank is remarkable. This tank offers a top AND bottom filling method, a 2.5mL juice capacity, Dual Spiraled Bottom Coil Structure, and a Triangle Theory Airflow system. The implementation of a top and bottom filling method makes refilling your tank an easier convenience as you choose your preferred way of filling. The Triangle Theory Airflow offers a triple Cyclops airflow control system for a reduction in airflow disruption. The Dual Spiral Coil Structure was the icing on the cake. It covers a broader range of wicking surface for the production of massive vapor clouds.
