Pyrex DCT Tank Black 3.5ml by SMOKtech
The new SMOKtech DCT tanks are made with Pyrex Glass and sheathed in aluminum. The aluminum sheath is windowed so that you can see the level of your liquid. The Pyrex Glass is used to protect against acidic eliquids and will also provide you with a cleaner vape. At the bottom of the tanks there are locking flanges which lock your cartomizer securely.
