The installation of the car glass case does not require any additional auxiliary tools and will not damage the original interior of your car. The glasses case comes with a telescopic clip that allows the glasses case to clamp the sun visor tightly, not loosely. Easy to Use - The glasses case features a push-pull switch, which is more convenient for one-handed operation. It can ensure that it is firm and will not fall off while driving, and it is easy to pick and place. The inside of the glasses case is lined with flocking, and the soft surface of the fine fiber fleece can ensure that the lens is not scratched. Multifunctional - The telescopic clip that comes with the glasses case can be attached to the sun visor and also placed in the pocket or on a flat surface that can be clamped. Durable Material - The glasses frame and sunshade housing are made of high-quality ABS environmentally friendly materials, which are resistant to pressure and falls, and feel more comfortable.
