Description: � xtr4 is the strongest screen protector from zagg. it�s fortified with graphene, and it�s been tested up to 11x stronger than traditional glass screen protection. (1) it�s also our most technologically advanced screen protection with blue light filtration to improve eye comfort and sleep, anti-reflective technology for richer colors, and a dust-free installation process. 11x stronger: xtr4 screen protection, fortified with graphene, has been tested up to 11x stronger than traditional glass screen protection. (1) fortified with graphene: graphene is one of the strongest materials in the world. improve eye comfort and sleep: xtr4 is the world�s first screen protection with radiance protection factor 60 technology that filters blue light which can disrupt sleep. (2) enhances color vibrancy: anti-reflective technology increases transmitted light to improve screen clarity and enrich colors for deeper blacks, true blues, and more vibrant reds. enhanced scratch protection: xtr4 has a nano-infused surface that makes it incredibly hard and scratch-resistant. maximum touch sensitivity: xtr4 has an sio2-enhanced coating for maximum touch sensitivity and a super smooth surface for fast, frictionless swiping. easy, dust-free installation: applying xtr4 is easy with the anti-dust adhesive and ez apply installation tray that ensures precise alignment. fingerprint scanner compatible: xtr4 works with in-screen fingerprint scanner. recycled glass content: xtr4 is made with up to 30% recycled glass. (3) t�v rheinland certified green product mark: xtr4 is made with up to 30% post-consumer recycled glass, its installation tray is made from 100% recycled content, and its packaging is 100% recyclable. fsc certification: xtr4 packaging has been certified by fsc, an organization working to protect healthy forests. anti-microbial treatment: anti-microbial treatment protects the screen protector from degradation by microorganisms. limited lifetime warranty: we will replace xtr4 for wear or damage for the length of your device�s life. (1) tests conducted by a 3rd party independent lab; tested up to 11x stronger than traditional glass screen protection. (2) measured at (440-435nm) 3 recycled material is certified through a third-party mass balance allocation process.
