The Devia Intelligent UV Protective Front Film is a clear screen protector designed to shield your device from daily wear and tear. Using a UV-cured material with a hardness of up to 5H, it provides a durable barrier that resists scratches and abrasion. You can choose between a 0.19mm or 0.25mm thickness depending on your preference for profile and protection. This film features a 3D fit to ensure it contours naturally to the screen's edges. To secure the bond, the application requires a UV lamp to complete the curing process. Each sheet measures 12cm x 18cm and this pack contains 20 pieces, making it a practical choice for those who want a precise, long-lasting fit for their display.
