Inside out / Keyboard

Keyboards which we are using are swarming with harmful germs along with dirt.
According to institute's research, it says that the germs on a keyboard due to fine dust are 150 times more than those of a toilet.
But we use the keyboard without awareness of the fact.
According to the institute's solution,it says that even only not piling up of dust has more than 60% of germ breeding control effect.The concept of this keyboard is to prevent the infection by germs from fine dust, by turning it upside down for dust not to be piled up when it's not in use.
