3D Rainbow Effect: The mosaic window film is colorless and neutral in color. Under light, it will display different colors. When the sun shines, the film will bring beautiful rainbow colors into the room. Thus, it can better decorate your home. Privacy Protection: The opaque window film offers privacy while still allowing light to pass through. Privacy is determined by the light intensity. The stronger the sunlight, the better the effect. (Use in bathrooms or windows without light is not recommended.) Anti-Glare and Sun Protection: Blocks most glare and 96% of harmful UV rays, also protecting your furniture from fading and aging. At the same time, it still allows sufficient sunlight into the room. Glue-Free and Reusable: The glue-free design reduces harmful rays. No residue is left upon removal, and it can be reused multiple times. The decorative film can always be applied and removed. Easy to install: Thanks to static cling, the self-adhesive films can be applied to windows as long as the protective film is removed and plenty of soapy water is sprayed on. Follow the installation instructions, and the film will adhere firmly to the glass. Important: When installing, please leave a gap between the edge of the window and the film (for example, if the window size is 20 x 10 cm, please cut the film to 19.5 x 9.5 cm). It cannot be applied directly to the window frame, as it will peel off easily.
