The Two-piece e cigarette:
The size of a regular cigarette
The two-part e-cigarette looks the most like a normal cigarette in appearance. The e-cigarette consists of a rechargeable battery and a cartomizer.
A cartomizer is a cartridge that is filled with liquid and equals about 15 to 20 cigarettes (depending on the brand). After use, it can be used for residual waste.
A two-piece e-cigarette has no control buttons and can not leak.
