Seidio's VITREO is a tempered glass material that utilizes advanced technology to shield and protect your Samsung Galaxy S III's screen. Made from a high grade glass with a 9H hardness rating, VITREO™ is shatterproof, allowing it to absorb more impact than your regular PET screen protector and prevent damage from occurring to your screen. The VITREO™ surface feels just like the device's screen without interfering with optical clarity while giving you an extraordinary level of protection. The design and lightweight material will provide peace of mind no matter what comes in contact with your device.
