What is the tool for piercing ears?

Hit yourself in the ear.

First, put the ear nail sterilized with alcohol on the gun specially used for pricking the ear, just like loading a bullet, and then aim the gun at the position where the ear needs to be pricked. Bang, for one second, there is not much feeling. The earring on the gun hit the ear. There will be no bleeding. At that time, I will feel that my ears are very hot and not too painful. It may hurt a little the next day, so pay attention to disinfection.
