This beautifully polished chrome SmokTech UDCT Cartomizer Tank stands above the classic DCT's. Like the dual coil tanks before it, the UDCT is a large clear tank, for great visibility, with polished chrome top and bottom. What makes this tank stand above its predecessor is the locking bottom plate.
The locking bottom plate, locks the center cartomizer in place, preventing the tank from sliding off of the cartomizer. This makes the UDCT great, even for carrying around in your pocket.
The small version hold 3.5 mL of eliquid and the large version hold 6 mL of liquid
