These refillable e-liquids pods have a 2ml capacity and have been designed for mouth to lung (MTL) style vaping. Removing the mouthpiece will reveal two juice ports, for quick and clean refilling. Each pod is fitted with a 1.2ohm vertical coil, that offers a restricted draw and discreet cloud production, as well as a boost in flavour. The in-built 1.2ohm coil is a perfect accompaniment for 50% VG / 50% PG e-liquids, including Nic Salts. Designed with parallel coils to give better flavour, bigger clouds and a smoother throat hit.
