Screen protector film made from PMMA (Polyethylene) and PET (Terephthalate) for your mobile phone. Thermoplastic material that does not break, equipped with adhesive, easy to install, and leaves no bubbles. The high elasticity and anti-slip structure ensure excellent durability. The surface of the tempered glass has a hardness of 9H, three times stronger than a regular screen protection film. Items like knives and keys will not scratch the tempered glass. Note: This is not glass.
