OG,a thoroughly upgraded new tank! This is a tailored tank for the customer
who seek pure flavor and huge vapor. High accurate model and all-in-one-shaped surface showed gentle and
dynamic curve design.. The mesh coil which has larger heating area to speed heating process brings you fantastic vaping
experience. Even though NuNu is non-replaceable coil, but the price of whole tank is the same as a coil. Undoubtedly,OG is a
revolution of traditional tank.
