These are the Kanger OCC (Organic Cotton Coil) Vertial Coils. The Kanger OCC Coils are the replacement coils for the Kanger Subtank family of tanks.
These are the new genuine Kanger OCC Coils for the Kanger Subtank Mini & Kanger Subtank Nano. The new Kanger OCC Vertical Coils are absolutely wonderful and perform better than the older version - the cotton wick provides the purest flavor and the coil head design is very efficient. These Kanger OCC Vertical Coils are vastly improved from kanger's previous coils and produce an amazing vape even for thicker eLiquid.
