【Compatible Models】Insta360 X4 【High-Quality Materials】: This product uses high-transmittance, corrosion-resistant Bayer 2805 PC material from Germany, coated with an anti-reflective film, a hard film, and a waterproof film, which more effectively protects the camera lens. It adopts highly transparent and corrosion-resistant materials, is scratch-resistant, wear-resistant, and features an anti-static design to prevent dust from adhering. Antibacterial treatment suppresses the growth of bacteria on the surface of the lens film. Recommended for those who want to keep their lenses and screens clean. It will not be scratched within the scope of daily use. 【Prevention of Air Bubbles】: The lens of the lens protection film is coated with a waterproof film layer, and the dripping angle is 115 degrees, so water droplets do not remain on the surface of the lens and do not affect the shooting effect. The water-repellent coating of the screen protection film repels water, protecting the screen. Automatic bubble absorption makes it difficult for bubbles to enter when the film is applied. The smooth screen has anti-fog, anti-deformation, high-temperature resistance, water-repellent, oil-repellent, and anti-fouling effects, allowing you to wipe away dirt without leaving any residue.
