These are replacement pods for your SMOK NOVO Kit. To fill a NOVO pod, simply pull out the rubber stopper from the side of the cartridge, squeeze your e-liquid through the filling slot, then replace the stopper firmly. Make sure to leave the pod to stand for 10-15 minutes if this is your first time filling it - this allows the e-liquid to soak into the wick fully.
SMOK NOVO pods come in packs of 3. There are 4 options to choose from - 1.2ohm, 1.5ohm, 0.8ohm and 1.4ohm (ceramic coil). Higher resistance coils (1.5ohm) are better suited to high PG liquids with a high nicotine content. Resistances closer to 1.0 work great with 50% VG, 50% PG blends.
