do without
The tempered film does not need to be removed when selling mobile phones. Because for selling mobile phones, selling mobile phones is the mobile phone itself, and it has nothing to do with whether the mobile phone is affixed with the tempered film. As long as the tempered film is not damaged, it does not need to be removed, and because the phone has been used for a period of time, the tempered film will be very strong, and it can also affect the screen. So selling mobile phones does not need to remove the tempered film.
Do you want to take down the tempered film can not take it down? Because the tempered film can't be used again if you take it off.
