I posted earlier about buying the safe cig. So it appears I have found a place to buy the cartomizers, but was wondering, where is the best place to start to look for e-liquid to fill them? A good well, rounded selection that I know will work with what I get. Do all liquids work in all carts? The brand from what I can tell is the nr4108 or something similar to that. Thanks to those that helped me in my previous post!
