It is very easy to install by simply adjusting the position and sticking. Comes with double-sided tape, so you can use it immediately after you receive it. Be careful not to expose injury to the edges during installation or use. As this is a delicate product, please check for scratches and damage when you receive it, and check the installation position before installing it. Please be aware that there may be slight processing or additional adhesion of double-sided tape due to differences in solid products.
