Rainbow effect: This stained glass effect window film features a beautiful tulip pattern with vibrant colors. When sunlight or artificial light shines on it, it creates a beautiful rainbow effect, making your interior space elegant and beautiful. Note: The frosted film itself is transparent and colorless. The principle of a rainbow is the reflection and refraction of light. Semi-privacy protection: This frosted window film provides semi-privacy protection by blurring the view from the outside and blocking visibility. At the same time, it lets natural light into the room, creating a private and comfortable space for you. (Semi-privacy film is not recommended for use in bathrooms.) UV protection: Our window film also blocks 84% of UVA and 99% of UVB, reducing harsh light, helping you work and read during the day, and preventing furniture from fading and premature aging. Easy installation: This privacy film uses electrostatic adsorption for installation. It can be easily installed with just simple tools and plenty of clean water (soapy water is better). It can be installed and removed repeatedly without worrying about damaging the window or leaving residue. (Be sure to remove the protective film before installation.) Wide application: This rainbow window film is suitable for smooth, flat, and clean glass surfaces. Widely used on clean and smooth glass surfaces, such as front doors, kitchens, living rooms, dining rooms, offices, hotels, classrooms, corridors, etc.
