For use with Clean Cig Starter Kits, these atomizing cartridges give the user a traditional satisfying full flavor. Clean Cig uses a two piece design, consisting of one battery, and one atomizer or atomizing cartridge. This ensures that every time you replace the cartridge, you're getting a new atomizer and new clean cartridge at the same time. Unlike some older 3-piece designs, you never have to worry about clogs, build up, or refilling used cartridges. These atomizing cartridges are offered in four different levels of nicotine. Extra High (24mg), High (18mg), medium (14mg), and low (10mg). One package includes five cartridges. Packaging design may differ from image shown
