Instructions for use: Shake the tank up and down before intercourse, insert the small end of the guide rod into the small hole of the nozzle at the upper end of the tank, invert the tank, and slowly insert the large end of the guide rod deep into the vaginal cavity. The guide rod should be inserted 6-8 cm into the vagina. Press the nozzle with your index finger until the foam sprays out and fills the vagina (just overflowing from the vaginal opening), and then slowly pull out the guide rod.

Rehabilitation guidance: The guide rod should be cleaned with water after use and can be used multiple times. Use it once within 1-5 minutes before intercourse and once after intercourse.

Which method is suitable for you varies from person to person. The safest and most economical contraceptive method is to use condoms, which does not harm the body.

I have used invisible condoms many times and can explain them to you. The invisible condom is a new contraceptive product. This foam contraceptive method became popular in the United States in 2004. It can not only kill sperm and various viruses, but also is invisible and shapeless, and its presence cannot be felt at all. It is vividly called the "invisible condom". When diluted 6 times and 30 times, it can cause sperm mortality rate to 100% within 1 minute. The unique dual-effect shielding contraceptive method of the invisible condom, on the one hand, the foam fills the vagina and cervix to form a physical barrier to prevent sperm from entering the uterus; on the other hand, the surfactant RH4 dissolves the sperm lipid membrane and inactivates the sperm, thereby achieving effective contraception. This product has obvious advantages. First of all, it quickly and efficiently destroys the surface tension of sperm, thereby killing sperm and a variety of sexually transmitted diseases and viruses; it quickly kills sperm and a variety of viruses, and has a good effect in contraception and infection prevention. Secondly, the foam fills the vagina and cervix, greatly reducing the activity of sperm and further preventing the combination of sperm and egg; thirdly, the foam forms a protective film on the vaginal wall, effectively preventing possible virus invasion; at the same time, the foam also has a lubricating effect, which can reduce the chance of infection. The foam is soft and delicate, non-irritating to the vagina and skin, and you can't feel its presence at all. In addition, the foam forms a protective film on the vaginal wall, which not only prevents damage but also enhances lubrication and increases interest. In addition, since it is not absorbed by the human body, does not enter the blood circulation, and does not participate in metabolism, it is eventually excreted from the body along with vaginal secretions and has no negative effects on the body.

The choice of contraceptive method is very important, especially the foam contraceptive method is very popular now, and the foam contraceptive method can greatly increase the chance of contraception. Therefore, people who want to use contraception can try the foam contraceptive method to make a choice. This can well ensure the chance of contraception and avoid the occurrence of accidental pregnancy.
