This screen protector film is designed to safeguard the display of your audio player or smart earbud charging case. It features an oil-repellent outer design that effectively protects the screen from fingerprints and smudges, ensuring a clear view. The film is also waterproof, providing an additional layer of protection against splashes and moisture. It is easy-to-apply, with a clear, transparent finish that maintains the original screen clarity and touch sensitivity. The application process involves wiping the screen, removing the No. 1 release film, aligning and pasting the protective film, and then removing the No. 2 protection label. This product is compatible with devices similar to the JBL earbud charging case with a display, as shown in the images.
