LIFE PROTECTION PRIVACY - Black window film blocks light and the black surface can darken your room. And gives you a high level of privacy. BLOCKS UV RAYS - Opaque window films block UV rays, protect your skin from radiation and reduce fading and aging of furniture. WIDE APPLICATION - Self-adhesive blackout window film is mainly used on smooth glass surfaces, perfect for use in bedrooms, bathrooms and offices, ideal for shift workers, doctors, students and babies. Warning - Since the self-adhesive wallpaper is self-adhesive, there is an adhesive coating on the back and the adhesive has a certain smell. After the wallpaper is produced, it is sealed and packaged with plastic (there is a lot of ink and there is an ink smell). Customers who are very sensitive to odors may experience a slight odor after unpacking. This is normal; the odor will gradually disappear after unpacking and application. We use environmentally friendly stickers, water-based ink, etc.
