Sterilized cotton balls are alcohol cotton balls.
Alcohol cotton ball is made from sterilized absorbent cotton ball by absorbing medical alcohol, which has the effect of disinfecting human skin and preventing infection.
Alcohol is very volatile. If you want to keep the concentration of alcohol cotton balls, it should be stored in a fairly sealed container. In daily life, you can buy a portable independent package, which is not only portable, but also better preserved. There are two types of packaging in the market: external tweezers and internal tweezers. The included tweezers are placed in the alcohol cotton ball packaging to effectively avoid secondary pollution during use.
