1. Look at the tape. The real drawstring is a regular and uniform linear wax seal, and the fake one without wax seal looks as transparent as the plastic film next to it, or it is poorly made and uneven.
2. Looking at the folding direction of the cigarette paper and plastic film at the upper and lower ends, the outer layers at both ends of the real cigarette are folded to the opposite side (that is, the "YUXI" side), while the upper and lower ends of the fake cigarette are folded to one side.
3. Look at bronzing. The bronzing of the characters and borders of the trademark on the front and back of the real cigarette is smooth and even, and there is no paint dropping phenomenon. The intersection of the word "jade" is straight and has no rounded corners, and the width of the border lines is the same; The bronzing characters of fake cigarettes and the lines of the frame are slightly narrower due to shrinkage (the wider the bronzing is, the more difficult it is to flatten, and the easier it is to lose paint), and the paint is not flat, and there are some drops of paint. There will be rounded corners at the intersection of the word "jade" or the letter "X", and the width of the frame lines is not consistent.
4. Look at the side seal. The side plastic film seal is flat and bubble-free, which is true smoke, and vice versa.
5. Look at the two triangles folded when the bottom cigarette paper is packaged. Its vertex angle is greater than 11 degrees, which is very different from that of an isosceles triangle (inclined to one side). The concave part of the triangle (relative to the sealing surface) is not obviously fake smoke.
6. Unpack the package, take out two cigarettes, and look at the inner tin foil paper to see if there is a machine indentation (full circle) about 8mm from the top. Fake cigarettes have no indentation.
7. Look at the filter tip. It can be clearly seen that the two circles of small holes are fake cigarettes. If you can't see it, take a sip of the cigarette and put it in your mouth. Squeeze the middle of the cigarette with your fingers to prevent it from breathing, and blow the cigarette in your mouth into the filter. Those with two circles of black spots are real cigarettes, and those without black spots are fake cigarettes.
