["【100% Blackout Material】: Our opaque light-blocking film blocks strong outside light very well, making the room darker so you can enjoy darkness during the day and get a good night's sleep.", "[Effective Thermal Insulation and Heat Control]: Made up of 3 layers of thermal insulation fabric (double-layered aluminum foil + pearl cotton layer), thicker than other window films, can effectively reduce the transfer of external heat, ensuring thermal insulation in summer and heat protection in winter. This keeps the room warm in winter and cool in summer, helping to save electricity and reduce air conditioning costs.", "[Design with Rounded Corners]: The black design with rounded edges is very exquisite and smooth, not only greatly improving the tear resistance and lifespan of the window film, but also perfectly matching your glass without damaging it.", "【SIZE & DIY】: The 30-155 cm wide blackout film fits perfectly on any window or door. For example, windows that open inwards and outwards, sliding windows, specially shaped windows, and triangular windows. The lightweight material also makes it easy to trim for smaller windows.", "【Wide Range of Applications】: Window protection film is suitable for all smooth and clean glass surfaces in living rooms, dining rooms, bedrooms, bathrooms, kitchens, balconies, closets, pergola skylights, glass doors, hotels, offices, lobbies, classrooms, etc. Double glazing, frosted glass, and other treated concave and convex glass are not suitable."]
