This is a new version of the DCT that holds your DCT cartomizer in place. There is a grooved channel on the bottom to hold your cartomizer and keep it from spinning. Then to ensure that your tank does not slide out inadvertently a cap screws on the bottom locking the cartomizer in place. You never have to worry about the cartomizer unseating itself.
This tank is made with a combination of chrome top and bottom with a plastic window in the middle to view your e-liquid level.
Please note: There is no warranty, returns, refunds or exchanges on cartomizers.
