Excess drip tips for all cartos color coded accordingly...which worked for a while, till I got 5 tanks on the go and numerous cartomizers and atomizers...now its just a giant s#&t show, random cartomizrs with no clue whats in there till I wash them out and get some random taste, my room looks like some kind of weird junkie with tweezers, scissors, tanks, syringes and needle nose bottles laying all over the place..gotta love vapeing.
