Suorin Air Pods function in the same way as a tank or atomizer. They contain e-liquid and vaporize the contents creating the vapor you inhale through the mouthpiece of the vape device. The Suorin Air replacement pods hold 2ml of vape juice. These pre-built cartridges can be switched out in seconds and are generally good for four to five refills before they need to be replaced. Perfect for extended trips out-of-town. Be sure to order plenty!
