I want to do something similar in my homework recently, but I checked and found that ultraviolet rays seem to do more harm to the mobile phone screen, and then the plan is passed.

Great

Isn't UV ultraviolet harmful to human body?

It takes the most time to take a mobile phone every day, so it is necessary to disinfect it.

This? Ha, ha, ha, ha. I like it

Do you have any products? It's really good

Has the big brother sent it before? It seems that he has an impression.

It's beautiful
