It's normal that different pictures of smoking are printed on the same Marlboro cigarette case. So are the cigarettes I bought while traveling in Hong Kong, as well as pictures of heart disease and impotence. Domestic cigarettes are generally flue-cured tobacco, the material is flue-cured tobacco leaves, and the taste is relatively thin. Marlboro is a mixed cigarette (many imported cigarettes are like this). Mixed cigarettes are made by mixing several different kinds of tobacco leaves in a certain proportion, namely flue-cured tobacco (Virginia) and oriental tobacco (Turkey).
I'm not very clear about the issue of steel seal. Some manufacturers will put steel seals on cigarette cases, and these steel seals will have some information about the production date, including the production month, the manufacturer's machine number, batch number and so on. Each manufacturer's label has different forms, and its expression is obscure, and its meaning is incomprehensible to most people.
