Product Description: Please Read Carefully: - Installation instructions for these magnetic curtains are straightforward. They are mount-type curtains that cling to the car door frame and do not fall off. - To assemble, open the car door and place the sun shades on the window frame (the metallic part). The magnet will automatically snap into place. Note that the front window sun shades are tapered from end to end, ensuring no obstruction of side mirrors' visibility. Note: - These sunshades require the car doors to be open when placing them on the windows. Sitting inside the car or fixing with closed doors will not work.
