Window Clings are near photo quality and ideal for POP signage on glass or glass-like smooth clean surfaces. They are printed on a glossy material and can be used indoor or outdoor. Clear Window Clings are range in sizes from 3×3 to 12×18 and cling on the front side of the print. If your Clear Window Cling is intended to be viewed from the outside of a window, then the artwork must be reversed prior to submission.
