15 years later, I was an inventor.

I will now invent a button that will prevent mosquitoes from biting, because a special device is installed in the button. When the mosquito comes, it will emit a gas, but this gas will not harm the human body. The mosquitoes will smell. When this kind of gas is reached, it will flee, but it will not be able to run for a long time and it will die.

This button also has an automatic alarm system. When the gangsters came to your home, the buttons quickly spread the intelligence to the police station without hesitation, prompting the police to arrive.

If you ask how the quality of this button is, rest assured that the button is made of special plastic. Even if it is dropped on the ground and then stepped on it, the button will never rot.

This kind of button has a silver zinc battery inside. This type of battery is very cheap for me to sell here. You can buy two sections for five cents. The battery life is 2 to 3 years.

If you like, please feel free to go to my shop to purchase my patent!
