BodyGuardz SpyGlass Edge allows you to access confidential information on your Apple iPhone 11 Pro Max with complete discretion. SpyGlass Edge is an aluminosilicate tempered glass screen protector that works to protect your device in two ways. First, our aluminosilicate tempered glass is designed to absorb the impact of a drop and is stronger than soda-lime glass. This decreases the likelihood of a scratched or cracked screen. Second, a two-way privacy film is incorporated into the glass to obstruct the view of your screen from onlookers.
