if it's the best identification with the Longma laser anti-counterfeiting mark at the bottom, the image of the genuine laser mark is clear, stereoscopic and colorful. False ones are often blurred, the color of the image is monotonous, and even the dragon pattern is not clear. So far, we haven't seen fake goods making the same laser anti-counterfeiting mark as the real ones, so this is the first identification basis! Other smoky tastes, and the fact that the cigarette holder of yellow pine paper will appear light around the middle yellow after smoking are all the identification basis.
