       Antibacterial directions:  "COOSKIN" Antibacterial TPU keyboard protective film has been added nano-silver, which can kill 650 kinds of harmful bacteria. In the test, there were 330,000 Staphylococcus and 160,000 E. coli, after 24 hours we used the film, only  less than 10 Escherichia coli and Staphylococcus survived. Tests show that "COOSKIN" antibacterial TPU keyboard protective film can reduce 99.9999% of the bacteria number in 24 hours, which fully guarantee the health of the keyboard. Scientific research has confirmed that a large number of bacteria that can not be seen by the naked eye are hidden on the keyboard.

Among the bacteria there are many pathogenic bacteria such as Streptococcus and Pseudomonas aeruginosa and chlamydia trachomatis and so on. The Keyboard bacteria has caused some of the spread of diseases, which has increasingly seriously impacted people's health. "COOSKIN" Antibacterial TPU keyboard protective film can effectively kill the bacteria on the keyboard so as to completely solve the problem of the keyboard bacteria.

       ( Note: Scientists have found that silver’a abilities of killing bacteria in the state of nano have  produced a qualitative leap.That means, only a very small amount of nano-silver can generate a strong sterilization. Nano-silver can strongly inhibit and kill dozens of pathogenic micro-organisms , such as E. coli, gonorrhoeae and Chlamydia trachomatis, etc. )
