The Spigen GlasTR EZ Fit screen protector is built for users who put their devices through real daily life. Made from high-purity alumina-silicate (Al2O3 + SiO2) glass and strengthened through an ion-exchange process, AluminaCore delivers enhanced impact resistance over standard tempered glass — ideal for parents whose children handle the device, commuters, gym-goers, outdoor users, and anyone whose phone has survived previous drops or bumps. The 10H surface resists scratches from keys, coins, and sand that collect in pockets and bags. Independently lab-tested at 100% optical clarity, it preserves the vivid colors, contrast, and sharpness of your display, so photos, video, and games look exactly as intended — without the yellow tint or dimming common to lower-quality alternatives. The ultra-thin 0.28mm construction keeps touch response identical to the bare screen, with fast swipes, accurate taps, and lag-free multi-touch that matter most to mobile gamers, heavy typers, and stylus users on supported devices. Engineered for natural touchscreen response — with a measured dielectric constant of 6.14, AluminaCore glass passes your finger's electrical signal through more cleanly than standard tempered glass, with minimal interference Compatibility is confirmed across supported models, including the device's Face ID where applicable — unlock in low light, authenticate in apps and mobile payment, and use edge gestures without losing accuracy. The oleophobic coating reduces fingerprints and oil marks for effortless daily wiping. Installation is handled by the EZ FIT auto-alignment tray, which positions the protector correctly on the first try — built for first-time installers, gift-givers, and anyone who has struggled with misalignment, even in a car, office, or dorm. Precision-cut edges fit inside Spigen cases and most third-party cases. Engineered specifically for iPhone 17 Pro | iPhone 17 | iPhone 16 Pro. Each pack includes 2 screen protectors, each pre-loaded on its own EZ FIT installation tray — so both the first install and the backup go on with full tray guidance, not just the first — plus a squeegee, dust removal stickers, a microfiber cleaning cloth, and an installation manual.
