"Honey, I shrunk the SubTank!!" The Subtank Nano manufactured by Kangertech, further shrinks the groundbreaking technology unveiled in the full size SubTank. Out of the box, the Subtank Nano includes two OCC replaceable coils (a 0.5 ohm and a 1.2 ohm). The new OCC (Organic Cotton Coil) replaceable atomizers (made with organic Japanese cotton) provide a level of performance comparable to any rebuildable device. Incorporated into the design of the base is a phenomenal adjustable airflow system, which allows for a custom feel. With up to a 3 ml liquid capacity and an attention grabbing visual aesthetic, the Subtank Nano has definitely earned a spot in your collection!
