SMOK Dual Coil Cartomizer Tank (DCT) Set - 3.5ml. Includes a special cartomizer (SMOK DualCoil DCT2 1.5ohm) with built-in flange and a drip tip.

 
The SMOK Dual Coil Cartomizer Tank (DCT) Set - (3.5ml) is one of the coolest cartomizer tank system on the market. Designed to fit 510 threaded devices.  These are simple to use, easy to fill and less accident prone due to the special dual coil cartomizer with built in flange. This flange prevents the cartomizer from slipping out of the tank when you pull off the drip tip. 

Cartomizer Specs:
Two 3.2 ohm coils run in parallel giving a total resistance of approximately 1.5-1.6 ohms. These produce huge amounts of vapor and great flavor due to the larger heating area of the dual coils and have less potential to burn due to the higher individual resistance of each coil. New improved filler material is more absorbent and provides better wicking to the coils.
 
They are easily refilled just by sliding the carto down below the top end cap, then dripping into the tank, being careful not to fill into the carto itself. 
 
Remember to keep them WET! They may burn if you run them too dry! You will need to presoak the cartomizer before use.
 
Due to the nature of cartomizers, we cannot offer warranty except for DOA.
