The Nillkin Guardian is a tempered glass screen protector designed specifically for the iPhone 13 and iPhone 13 Pro. Its primary feature is a built-in privacy filter that limits viewing angles, ensuring that your screen content remains hidden from people looking at your device from the side. This protector is crafted from 9H hardness glass with a thickness of 0.33mm, providing a durable shield against scratches and impacts. The 2.5D curved edges and full coverage design allow it to blend seamlessly with the phone's display, maintaining a smooth feel for your fingers as you swipe across the transparent surface.
