This product can be applied two different ways. Mounted to the outside when windows are tinted or inside of window when glass is clear (also known as a reverse window cling). Window clings make a great way to advertise an upcoming sale without damaging your display cases, windows, or any other smooth surfaces. Easy to apply and remove without leaving any adhesive behind. We offer unlimited colors and copy. White static cling can also be used as a temporary backlit material. Details for applying can be sent upon request.
