2, look at the batch number: genuine perfume has at least one batch number, located on the outer packaging or perfume bottle cover. If the bottle cap and the outer packaging have batch numbers that match, it can basically be judged as genuine. Generally, fakes will not have a batch number, but it cannot be completely ruled out.
3, look at the nozzle: if the perfume has a nozzle, the nozzle of the genuine perfume is stuck, unless it is difficult to pull it out, and the counterfeit perfume is easy to open, and many of them are twisted, so the nozzle is easy to unscrew the bottle.
4, look at the capacity: the capacity of genuine perfume test-tube perfume is generally around 2ml, mainly 1-2ml, not as much as 5ml, 5ml will generally be made into Q version perfume, not as test-tube perfume, if you see more than 5ml of test-tube perfume, you can basically judge it as a fake.
5, look at the straw: If the perfume has a straw, the genuine perfume straw is generally taught to work fine. The length of the straw is the same as that of the bottle, and the cross section of the straw just reaches the bottom of the bottle, not too long or too short, while the fake perfume often makes a long cross section due to rough workmanship and bends in the bottle.
6. Look at the liquid: the real perfume must be a clear, transparent and high-definition liquid, without any impurities, pigments and precipitates, showing its natural color. The liquid of counterfeit perfume is mostly turbid and has a low color.
7. Look at the seller: If the perfume is bought from a brand perfume shop and the seller has the authorization of the brand, it is more likely to buy genuine products; If you buy it online, you can go to the brand official website or the official mall to buy it, and the probability of buying fake goods is also low.
8. Smell: High-quality perfume generally tastes pure and can give people a pleasant feeling, while inferior perfume will have unpleasant smells such as alcohol.
