VooPoo’s PnP-X empty pods are specially designed for the Drag X PnP-X kit and the Drag S PnP-X kit. This pod cartridge is clearly visible and has a huge e-liquid capacity of 5mL. Topped with an airflow control ring, the PnP-X pod has infinite airflow control for your coil to vaporize. With the fill button on top, press the semi-hidden button and twist to the left, then pull out the silicone cap to fill. Compatible with all PnP series coils, it features a leak-proof design to contain the e-liquid for a clean hand.
