iPhone 12 Anti-Blue Ray Tempered Glass Screen Protector

This is a ultra-thin layer of chemically treated tempered glass with 2.5 D Edge Polish and 9H Hardness rating. 9H Hardness rating even exceeds the hardness of steel.This screen protector is made of Shatter-proof glass and has an Oleophobic coating that prevents scratches, smudges, fingerprints and other contaminants.
Once the glass is released on the phone, the silicone adhesive doesn't allow any bubble formation. If the glass is removed, it doesn't damage the surface of the iPhone in any way. It is reusable. Even the sharp objects like knives can't damage this tempered and processed shield. If broken, the Tempered Glass breaks into small pieces that are not sharp, making it safer than other glass products.
