Frosting sticker is a type of adhesive window film that can be applied to any smooth glass surface. Front doors, shower screens, office partitions, mirrors, french doors and signage are areas where these stickers can be applied. The most important reason why most people use frosting stickers is privacy. They give a modern decorative look to your glazing, at the same time providing security and privacy and allowing natural light into the rooms. They are also an inexpensive and functional alternative to curtains and blinds.
