SMOK RPM 4 Pod is a set of transparent cartridges made of PCTG, used for maintenance of SMOK RPM 4 Kit. There are two types of pods: one for RPM 4 RPM Pod using RPM coil, and the other for RPM 4 LP2 Pod using new LP2 coil with leak-proof structure. Both pods have a capacity of 5ml, enough large capacity, which can provide a continuous atomization experience and avoid the frequency of repeated filling e-juice.
