What are male cotton swabs for?

As we all know, cotton swabs are widely used, but most of them are still used in medical treatment. Nurses in the hospital will use cotton swabs to disinfect the skin surface with alcohol before injection, press the pinholes of cotton swabs when pulling out needles, and dentists will temporarily replace them with cotton swabs when there is no tongue depressor around.

In addition to these cotton swabs, they can also be used to clean the gaps in mobile phones, and so on. I have to say that cotton swabs have many functions. I want to say here that boys may buy cotton swabs to clean their ears or clean some gaps in their mobile phones. In addition, they are also used in the application of drugs. After all, drugs have three kinds of toxicity, and there must be some safety hazards if you accidentally eat them by hand. Boys buy cotton swabs. That's all I can think of at the moment.
