Compatible models: iPhone 11 Pro Max / XS MAX This set includes two films, one for the front and one for the back. 【Reinforced Tempered Glass Film】Beware of imitations and low-quality products. Made with high-quality materials to reduce impact and minimize screen damage. It has a surface strength about 5 times stronger than ordinary glass films and a surface hardness of 9H, which is harder than a knife, protecting your screen from scratches and fingerprints. 【Anti-Shatter & Anti-Fingerprint】Features a shatterproof film, so even if the glass breaks, the fragments will not scatter. It is resistant to fingerprints and dirt, providing a smooth operating feel, and any attached dirt can be easily wiped off. 【Bubble Prevention & Self-Adsorption】The film's adhesive surface has a silicone coating with excellent adhesion, allowing it to self-adhere. Simply align and place it, and you can apply it without bubbles. Even those who are not good at applying films can easily apply it. Thank you for viewing!
