These dual coil cartomizers are XXXXL sized, with the extra 2.5mL liquid capacity and TWO atomizer coils, these cartomizers produce a lot of vapor.
The dual coil design allows the heat to be evenly dispersed inside the cartomizer, properly using all the liquid without creating a dry burning flavor. It is almost leak proof and can be used for more than a day's worth of smoking. It comes in two different colors- stainless steel and black. These work fantastically on the Joye EGO/EGO-T batteries or most other big battery models. We do not recommend that you use them on regular 510 or Mega 510 batteries. You will get one sealed blank SmokTech XXXXL Dual Coil 1.5 Ohm cartomizers.
