An e-cigarette (or electric cigarette, e-cig, vape pen, vape, mod, tank system, ends - popular ones have many names) is a battery-driven device that makes smoke-like vapor from e-juice. E-cigs come in many shapes and sizes. Some are made to look like regular cigarettes, cigars, or pipes, others resemble regular vaporizers. But the thing they most have in common is that they are made to be descreet and easy to bring with you. We have both pre-filled disposables and refillable e-cigarettes with accessories.
