3-Pack Screen Protector for iPhone 17 Pro SmartPull Box Pro Installation System 5X Stronger Reinforced Glass Advanced Shatter Resistance

5X Stronger Impact Resistance with Reinforced Glass StructureLithium-aluminosilicate glass combined with triple strengthening and deep ion-exchange (DOL 69 m) significantly increases structural density and impact resistance handling high-force drops with reduced breakage risk. Advanced Shatter Resistance with High Compressive StressSurface compressive stress 900 MPa and high-purity glass composition improve fracture resistance limiting crack propagation and reducing fragmentation under impact. Engineered to Resist Everyday Scratches (9H
Hardness): Mohs hardness 6 and reinforced surface layer resist scratches from keys coins and metal friction maintaining long-term clarity and surface integrity. High Transparency with Precision Optical Processing93% light transmittance combined with high-precision polishing and AF coating reduces haze glare and distortion for clear stable visuals. Refined Installation System with Bubble-Free Precision FitIntegrated alignment structure ensures accurate positioning and controlled application pressure enabling dust-free bubble-free installation while maintaining full edge compatibility with most phone cases.
