Digiflavor S G MTL Tank brings multiple airflow adjustments with the flavor booster GeekVape G Series Coil. Siren-style deck design prevents liquid from leaking after using for long time. Leakproof top cap double secures the liquid from spilling out. Anti-lock function provides an easy deck open experience. A precise and slide-to-adjust linear airflow setting creates smoother flavor for both MTL and RDL! Concealed airflow inlet design supports up to 10 kinds of airflow settings. The tank’s 4 vertical-row slots let coil cotton wick better and prevents the coil from getting burnt, which increases its longevity.
