The Preserver Privacy tempered glass protects your screen from prying eyes using micro-blind technology, so only you can see what’s on your screen and bystanders see a blank display. Made with high quality materials, the Preserver Privacy also provides an incredible 9H level scratch protection, effectively preventing scratches from keys, sand and other hard objects. The high clarity glass also features an anti-glare and anti-fingerprint treatment, keeping your screen clean and easy to see in brightly lit environments.
