The anti-gravity case can be easily attached to any smooth surface such as glass, mirrors, whiteboards, planks, smooth metal, computer screens, tiles and more. Make sure the phone case is clean and free of dust when in use. If the surface has poor dust adsorption, please wipe it off with a wet towel. After the water is dry, the adsorption can be restored. When the adsorption function is not used, it can be attached with a backing, which is not only dustproof and beautiful, but also protects the adsorption surface and prolongs the service life.
