Sagre film without glue for sticking on windows with just plain water. I cleaned the window, wet it well and then carefully placed the product. I spread it well with a kitchen spatula to remove any bubbles and excess water and left it to dry in peace. It is still there in its place and I have the impression that it will stay there all summer, when I want it to block the strong sun inside the house. I have large windows. Children saved.

It is not a sticker. It is a thin plastic smooth on one side and rough on the other for use in any drawer or cabinet. After pressing it, I tried to put it with transparent glue on a window but the glue leaves marks and the result is unsightly
