The Billow V3 has taken some of the best features of other tanks and incorporated them into this fabulous new design. These features include terrific airflow from dual cyclops slits with a stop design and a centre airflow beside the coil itself for even greater flavour. The juice flow control is operated by turning the top cap and will cater for most types of e-liquid to perfection. Filling this tank couldn't be easier, simply pull the top cap and squeeze your favourite juice in the convenient fill port. Lastly the all important build deck is a two post velocity style with a generous amount of room to build your favourite coils directly on top of the perfected airflow design.
