iLLumiShield - Sony Xperia Z1S Anti-Glare Matte Screen Protector HD Clear Film / Anti-Bubble & Anti-Fingerprint / Premium Invisible Crystal Shield &ndash; Free Warranty &ndash; [3-Pack] Retail Packaging This kit features 3x Matte Anti-Glare screen protectors for Sony Xperia Z1S along with a set of instructions, installation squeegee, microfiber cleaning cloth and the iLLumiShield lifetime warranty. Designed with High Quality PET film imported from Japan that consists of multiple layers. Each layer provides specific functions that allow the Matte Anti-Glare line of Sony Xperia Z1S screen protectors to outperform competitor products that use inferior materials and manufacturing processes. Anti-Glare technology refracts and disperses reflected light off your screen but allows projected light from your device to pass through without heavily distorting your viewing experience with stray colors. While other products appear visibly smoky or cloudy, the iLLumiShield Matte Anti-Glare line appears virtually transparent. The Anti-bubble silicone resin layer is self-adhesive which allows for an easy dry installation - no more hassle from handling spray solution that could potentially leak into the ports of your device and do damage. For optimal effect, install in a lint-free environment. iLLumiShield Matte Anti-Glare is a highly transparent, "glass-like" smooth and scratch resistant film that prevents bacterial elements, oil, and fingerprints.
