Our car rear window sunshade effectively blocks sunlight and UV rays: It consists of two layers of fabric. One layer is a semi-transparent gauze and the other is an opaque sun-blocking fabric. You can choose to close it completely or partially, depending on your needs. It effectively blocks sunlight, heat, and UV rays, keeping you and your family cool and comfortable at all times. Use only on the rear window! Do not use it to dry the windshield, as it may obstruct the driver's view. Magnetic design with steel frame: Our car curtain has 10 strong magnets at the top. The magnetic rear window awning is designed for steel window or door frames. Always check the surface finish of your window frame before purchasing. (If your window or door frame is covered with plastic or rubber, the magnets will be less attractive.) Please note that it is not compatible with Tesla's frameless windows. Perfect for travel: This parasol has a double-layer design. If you want to enjoy the outdoor scenery, you can tie the entire blackout fabric to the parasol with a rope. Keeping the partial blackout net open blocks some sunlight and UV rays without affecting your vision. It is perfect for traveling with a baby. Fits most car sizes: These car sunshades measure 67.8 cm x 50.4 cm. Since these car sunshades are adjustable, they fit almost all car models, such as sedans, SUVs, minivans, SUVs, and other types of vehicles. If you want complete sun protection, measure your car windows' dimensions before purchasing. Easy installation: Instructions: 1. Open the car door; 2. Attach the magnet of the sunshade to the metal frame at the top of the door/metal frame above the door. It can be installed on almost all car windows. Since this sunshade is made of soft fabric, you can easily fold it and store it in any compartment.
