Privacy Level: Opaque window films protect your privacy by blocking outside views, offering 90% privacy. This window film allows natural light to enter, keeping your room private while maintaining good light transmission. It's a clean, modern alternative to curtains or blinds. Rainbow in Light: The window film itself has no color. However, when light passes through it, it reflects a rainbow effect. As the light changes, so does the color. It can be applied to any smooth glass surface. No Adhesive: Easily removable without leaving any residue. You can apply and remove it repeatedly if it's not damaged or stained. UV Protection & Energy Saving: Eco-friendly window stickers keep your home cool in the summer and warm in the winter. They block 96% of UV rays, delaying furniture aging and fading. NOTE: Apply only to smooth glass; peel off the protective film before installation and thoroughly wet your window and the window film.
