There are different kinds of vape pens out there. The Vibe uses tanks that contain nicotine at 3.0% by weight.
Vape pen tanks are cylindrical and taper to form the mouthpiece. The Vibe’s tank is translucent to show the amount of e-liquid left inside.
Vape pens get their name from their pen-like shape. They are cylindrical like a cigalike—but thicker. Extra space for a larger battery, which is why the Vibe has a long-lasting 600mAh battery.
