The tempered, processed shield provides extensive protection from outside damages and scratches, including sharp objects like knives and keys. And it's laser-cut for a perfect fit. Oleophobic coating and the 9h hardness (high-grade glass) together prevent most scratches, smudges and fingerprints. A quick wipe restore your screen to sparkling clarity. The shatter-proof film minimizes damage when the screen is broken and helps to reduce damages in general. Once you release the glass on your phone, the silicone adhesive does all the work. No bubbles, no fuzz! Perfectly flat and pristine every time.
