What does tempered glass really mean? It means business! Well, and that this screen protector doesn't have time for life's Petty antics of scrapes, scratches, and dents. Plus, it comes with an easy applicator and cleaning kit. Trust us, installing a TUFF sheet yourself makes you feel more accomplished than someone who assembled Swedish particle board furniture in under 9 hours. Except this will ONLY take a few minutes... That's some TUFF sheet.
