The VooPoo PNP MTL replacement pods have been designed for use with a range of VooPoo kits, including the Argus kit and V Suit kit. Each pod holds up to 2ml of e-liquid and should be paired with MTL PnP coils, such as the PnP T coils, PnP R coils and some of the the PnP VM coils. Always make sure you check the max wattage output of your kit before selecting a coil.
