Using 0.5mm ultra-thin optical glass material with high transparency (over 90% light transmission) ensures clear imaging. A special treatment process enhances the protector's hardness to nearly 8H. Resistant to elastic pressure up to 8kg/m², it helps protect the LCD screen from sudden impacts. The double-sided adhesive provides strong adhesion. Easy to install. Performs reliably under normal high or low temperature conditions. Designed to prevent bubbles and peeling during regular use. Special optical glass effectively resists erosion from sweat, oil, and acidic substances, helping to extend the life of the LCD screen. The protector can be removed and reused as long as the double-sided adhesive remains undamaged.
