Common sense: How to identify condoms with the naked eye

　　1. Packaging box quality and pattern

High-quality brand-name condoms: The packaging box has good paper quality, the carton is strong, and the printing is beautiful and clear. In order to maintain the image of their brand-name products, they generally do not use very explicit or hot patterns, but try to appear more subtle or neutral.

Inferior condoms: The outer packaging box may have poor paper quality or blurry printing, and the packaging box graphics may be vulgar, sensational or even obscene.

2. Outer packaging logo
　　
High-quality brand-name condoms: The outer box is printed with the name, address, phone number of the manufacturer and distributor, production license, health license, batch number, and expiration date. Printed with the "CCC" logo, some products are also printed (or affixed) with anti-counterfeiting labels.

Low-quality condoms: vague or no labeling.

3． Small packaging aluminum foil
　　
High-quality brand-name condoms: printed with production batch number, production date and other reference marks for reference, and printed with the "CCCC" logo.

Poor quality condoms: vague or missing labeling

4. High-quality brand-name condoms: Condoms should be uniform in texture, milky white or dyed with colorants, uniform in color, and taste of natural latex or with added fragrance or medicinal flavor.

Inferior condoms: The latex may be impregnated unevenly, or may contain bubbles, impurities, or a foul smell, or the coloring agent may fall off.

5. Simple inspection method
　　
Condoms must pass electronic pinhole, water leakage, burst pressure and aging tests before leaving the factory. As a consumer, it is impossible to use professional instruments for testing, so you can use simple methods to check the quality of condoms.

Tension method: unfold the condom and repeatedly stretch it vertically and horizontally. High-quality condoms will not tear due to this.

For example, the inflation method: after inflating a high-quality condom, use the small sac at the front end as the midpoint, expand evenly, and blow it to 10cm, while the front end can still maintain a nipple shape.
