1. Packing box: First, check whether the words, patterns and signs on the packing box are clear, distinctive and complete, and whether there are typos, garbled codes and other problems. Authentic packaging boxes have exquisite handwriting, bright colors, clear patterns and high printing quality. On the other hand, the printing quality of counterfeit goods is usually poor.
2. Cigarette barcode: The barcode of genuine cigarettes is generally clear and complete, while the barcode of counterfeit products may be vague, false or missing.
3. Inside the cigarette case: The inside of a genuine cigarette case is generally dry, neat and odorless. However, counterfeit products may have problems such as odor, humidity and impurities.
4. Cigarette filter: Genuine cigarette filter has a solid texture, while counterfeit products may have a soft texture.
5. Tobacco taste: Authentic tobacco tastes pure, rich and non-irritating, while counterfeit products may taste rough and irritating.
