Ten strokes of the essence of the answer: divide the true and false cigarettes skillfully and look at a bag. The transparent paper of genuine cigarette sticks is flat, and the lap is ironed with a soldering iron, which is smooth and bright; The strip package is sealed by mechanical point bonding. Fake strips and bags are often packed with defective old crystals, which are uneven, smooth and flat; Lapping and sealing are mostly bonded by glue; The bag is loosely packed and feels uneven. Second, look at the cigarette case. The cigarette case is packed with transparent paper, and the pull head of the cable is in the shape of a small table, and the bonding is firm and flat. The transparent paper of fake cigarettes is uneven and loose, and the zipper is generally flat-headed, mostly without lead; The drawstring and the transparent paper are not bonded; The transparent paper of cigarette case is uneven after opening. Third, look at the trademark. The trademarks of cigarettes and cigarette packs are consistent, and the patterns and handwriting are clear; The fake cigarette patterns are printed roughly, with different colors, unclear handwriting, incomplete letters, and errors and omissions in Chinese Pinyin and English. Fourth, look at flowers. Cigarette holder flowers are generally printed into strips and boxes with the same manufacturer name and the same width. The joint is a combination of two thin strips, which is easy to open and will not break. The mouth flower of fake cigarettes is different from the manufacturer's name on the box, and the width is also different. Mouth flower is sealed with glue or paste, which is not easy to open. Fifth, look at the eye of a needle. Pinholes are left by mechanical packaging of cigarettes. There are two slits at the four corners of the bottom of the horizontal packaging box, and the slit on the side that is vertically wrapped after opening is a pinhole. But there is no pinhole in the manual packaging of fake goods, and the traces of scissors are obvious. Sixth, look at cigarettes. The famous brand filter has neat cut, no stubble, uniform cigarette rolling, moderate hardness, clear steel seal, machine number and month, clean cigarette surface and no smoke in the mouth; Fake cigarettes are the opposite. Seven, watch your mouth. The cigarette joint is full and airtight. Fake cigarettes generally have no filter paper, and the seams are loose and easy to leak. Eight look at tobacco. Tobacco stems are few, and after puffing treatment, tobacco oil is moist and shiny. There are many stems in fake tobacco, and there is even a mixture in tobacco. This kind of tobacco is dull and blue-brown. Nine smells. Tobacco has a special natural tobacco flavor. If fake cigarettes are perfumed too much or use inferior essence, they will smell unpleasant essence or dim aroma.
