Is the polarized film adhesive?

One side of the polarizing film is adhesive. The side with the "red label" is adhesive, the side with the "blue label" is not adhesive. Have written remarks.

The polarization film is covered with protective film, which must be removed before use.

I bought other polarizing films, and when I received them, there were already creases. How do you protect them?

Hard plate protection is used to ensure that the polarized films are in perfect condition.

What should I do if there are bubbles after installation?

We included wet-dry cloth and squeegee to help with a better fit.
