1 x User's manual
5 x Cartridges (Tobacco flavored with 2 High nicotine, 1 Medium, 1 Low, 1 Zero nicotine)
20 x Cartridge Refills (Choose the flavor and nicotine level below)

Each nicotine cartridge is approximately equivalent to 15 to 20 regular tobacco cigarettes, depending on smoking habits. Choose the nicotine level and flavor of your cartridges. If you smoke rolled tobacco cigarettes, we recommend a high cartridge. If you currently smoke light cigarettes, we recommend starting with the medium level of nicotine.
