Completely scratch-proof, shock-proof, and bubble-proof, iVisor Glass is practically a bullet-proof vest for your Galaxy Note 4's touchscreen. Made of IonGlassTM, iVisor Glass features an atomically-strengthened structure that is stronger than tempered glass screen protectors. It also features a new precision-tooled bezel tailored to your Galaxy Note 4's curved touchscreen to provide 100% edge-to-edge protection. While most screen protectors require a tedious installation process, iVisor's proprietary design allows for an effortless, bubble-free installation in seconds. Because IonGlass exceeds the hardness of tempered steel, the surface is nearly impossible to scratch, even with a knife. At 0.3 mm thin with rounded edges for fit your Note 4 screen, iVisor Glass blends in and virtually disappears on your smartphone screen. Once installed, you won't notice any difference in screen clarity and touch sensitivity.
