SMOK Novo 4 Pod Cartridge is only designed for SMOK Novo 4 Pod System Kit. The pod comes in two colors: Transparent Black and Transparent. Featuring a 2ml e-liquid capacity, these pods adopt a replaceable coil design for a cost-effective and eco-friendly vaping approach. They can be filled via the side fill port. Simply lift the rubber tab, insert your favorite e-liquid, and begin filling. Always allow time for e-liquid to saturate the coil before vaping. The integrated flat mouthpiece feels comfortable and satisfying every time you vape. Novo 4 Pod Cartridge itself uses a leak-free design - Bottom push-press coil installation. The inserted LP1 coil puts three silicone rings at a time, which will fill the gap and effectively prevent the liquid from leaking from the pod.
