Tempered Glass Screen Protector
The JJT Tempered Glass Screen Protective Film is protected by specially treated glass, and the Tempered Glass Screen Protector brings excellent scratch resistance to the screen. The Tempered Glass Protective Film is made of shockproof technology, which has the characteristics of anti-scratch, anti-fingerprint and anti-oil, which can greatly reduce the damage to the screen due to strong collision. The adhesive force of the silicon adhesive ensures that there is nothing between the screen protector and the screen, thereby improving touch sensitivity. Ultra-transparent glass can ensure a better clear image quality than ordinary Screen Protectors.
The surface hardness of the Tempered Glass Screen Protection Film is 9H, which is 4 times that of ordinary PET Film. Sharp objects (such as knives and keys) will not scratch the surface.
The Screen Protector has an "oleophobic and waterproof" coating to prevent fingerprints and other contaminants, making the screen protector easy to clean.
It has unparalleled touch and high responsiveness to touch, 99.9% transparency, transparent without bubbles.
