An E-cigarette refill cartridge is one of the typical components of an electronic cigarette. It is mainly designed to store flavored liquid solution. A cartridge is also called a mouthpiece in E-cigarette industry. It is usually small disposable plastic cup like piece affixed to the end of the vaporize cigarette.

The cartridge usually comes with a small plastic cup inside to hold absorbent materials which are saturated with flavored liquid solution that may contain nicotine. The air is able to flow around the inner cup and through a hole in the end of the outer piece. Thus, the electronic cigarette is able to provide the ability for suction to move the vapor into the user\'s mouth.

When the liquid in the cartridge is used up, it can be either be refilled by the user or replaced with another pre-filled cartridge. We at FIRST UNION primarily manufacture refill cartridge, which provides an economical solution to E-cigarette users.
