The Rune web camera cover is slim and perfect in today's age of internet security and privacy needs. It's made of ABS plastic with an adhesive that will not leave residue on monitors nor laptops. This web camera cover is thin enough to still allow most laptops to close properly. The sliding shutter easily moves to the side and allows a web camera to be visible when needed. Your logo will be printed front and center and you'll be top-of-mind every time your clients use their computers. The surface must be smooth and clean for the adhesive to stick well. Some treated glass surfaces may present adhesion issues.
