1. Look at “embossed” anti-counterfeiting: The three characters of the trademark on the outer packaging are convex, which is the case on the front, side, back and top. It's just that most fakes nowadays are imitated, and this method can only identify a very small number of fakes.

2. Look at the printing: Of course, there are very few fake condoms with blurry printing or reprinting, but fakes generally have a slight color cast, which is difficult for ordinary people to see. Only the real and fake condoms can be seen together. More obvious.

3. Look at the hot stamping illusion on the anti-counterfeiting easy-draw ribbon: The mark on the genuine gold ribbon uses illusion technology. At a certain angle, you can see an obviously brighter color, and the color changes at different angles. It changes, and the entire circle of anti-counterfeiting ribbons is like this.

The logos on fake condoms are generally non-colorful. Even if the fake condoms have a phantom color, the color is very light, not as bright as the real thing, and it is not visible on all four sides. Done.

4. Look at the date, batch number and other inkjet codes at the bottom: Large manufacturers all use laser inkjet printing, and you can see dot-like marks. Generally, private manufacturers of fake condoms cannot afford to purchase laser inkjet printers. Because a laser inkjet printer costs more than 200,000 yuan, many private fake manufacturers can only use printing instead of laser inkjet printing. The printing is It cannot be made into points.

Of course, today's big counterfeiters have already used coding machines, and their fonts are also dotted, but their fonts are smaller and thinner, and the colors are slightly lighter. Of course, this also requires some experience or comparison with real products.

The authentic one can easily tear apart the very similar fake on both sides without jagged edges. Its date cannot be scratched off with a fingernail (in contrast, the color is lighter and the font is thinner) but From the non-serrated part, the film is deformed and cannot be torn apart even if the force is applied very hard.

Extended information

Traditional condoms have safety flaws. While traditional natural latex condoms are effective in contraception, although condoms have a certain blocking effect on viruses, they can never effectively prevent viruses. . Condoms are safe for preventing pregnancy, but they are not safe for preventing viruses.

Condom products on the market mainly use natural latex, with natural cracks between 5,000 and 70,000 nanometers, which is enough to prevent human sperm heads with a diameter of 5,000 nanometers, but the diameter of HIV Only 120 nanometers, the diameter of human papilloma virus is between 45 and 55 nanometers, and the diameter of the large spherical particles of hepatitis B virus is 42 nanometers.

The size of various viruses is much smaller than the natural cracks of natural latex. Even if condoms are used correctly, it is still possible to be infected with sexually transmitted diseases.
