Then explain things, it is an electrostatic film (without adhesive) for glass, the use is simple:
Just take the measurements of your window, and then carefully cut with a cutter to have the right dimensions, it can be scary but it's super easy!
Of course, both height and width, this does not correspond to my window, so I had to make cuts to be three rectangle to fully cover my window.
It must then thoroughly clean the glass in order to have any dirt, and keep very wet in order to achieve the pose.
As this is a non-sticky product, we can take it a few times to ask the best.
In short, a result at the end really nickel, having much overlooked, and not being adept curtains that eats all the light, this is really translucent, that is to say that even 15cm of the window, it is impossible to be seen, not even we distinguish the silhouettes was outside, just the light passes, which gives a rather diffuse white light as a skylight.
The plus helping to achieve is that it has a support for cutting (grid overleaf) to make no mistakes, so if you have overlooked, or if you just want a more privacy, please!
