The Def Tanks are HERE. These are 30mm RTA's and are flavor MONSTERS. You can fit up to dual 5.5mm coils in it but wicking can be tricky at that size. It seems the perfect coils are dual 4.5mm coils. 

Every tank comes with a bag of spare orings, hex driver and 4 extra screws. 1 extra glass section and 1 bubble section for more juice capacity
