blu Rechargeable PacksWhat exactly is an e-cigarette?

We’re glad you asked.

There are two main components: the battery and the flavor cartridge. When you inhale on the e-cig, the battery is activated. This action heats up (without burning) the smoke juice contained in the flavor cartridge, and it’s then converted into a vapor. You inhale this through the flavor cartridge, and you exhale vapor.

blu eCigs® electronic cigarettes have an LED light that glows blue when you inhale to let you know that you’re free to vape and savor the flavor of that rich, satisfying blu eCigs smoke juice. It also informs those around you that you’re vaping and not smoking, and it signals to the world at large that you’re a forward-thinking person who prizes freedom and appreciates quality and high-tech design.

The flavor cartridge features an intake hole designed to maximize the draw and resistance of the vapor when inhaled, so it’s a satisfying experience. Take one slow, deep drag, and you’ll understand.
