Moshi's IonGlass is an atomically-strengthened glass screen protector that exhibits exceptional hardness exceeding that of steel. This makes IonGlass nearly impossible to scratch, even with a knife. Unlike a typical screen protector cut from flat sheets, IonGlass is a curved glass that is precision-molded to fit your device's touchscreen perfectly. This process creates smooth, edge-to-edge protection with a micro-bevel around the Home button for fast and comfortable unlocking via Touch ID. Completely scratch- and shock-resistant, Moshi's IonGlass is the most advanced glass screen protector that perfectly blends in with your device's display.
