The Cartridge is composed of inhaler and nicotine fluid container. There is 1ml of diluted nicotine fluid ready for atomizing in the container, with thickness of 1.8%. The nicotine fluid is purified from tobacco by biological technology, removing the harmful substances in the tobacco and keeping the harmless or useful substances, as well as adding different essence. It not only keeps the cigarette抯 basic function, but also removes the harmful substances.
