plastic contact for bathroom window

Would anyone know where I could locate plastic contact for a bathroom window to make it translucent?

Thanks for that. Will try them

I got it for my mam a few months ago in Woodies. If it is the same stuff it was only about 4-5 euro. Maybe it was a smaller roll. She only wanted it for a small glass pane on the top of the bathroom door to prevent people going up to the attic seeing into the bathroom.
