The leak-proof coil design of the new SmokTech LP1 Coils for the Novo 4 Kit makes a messy cleanup and wasting of liquid a thing of the past! When inserting the new LP1 Series Coil into the pod, the added silicone ring on the bottom of the coil fills in for any possible gap, effectively stemming the liquid leaking from the pod that results in a messy vaping experience and sticky hands! No one likes sticky hands.
