High-quality, standard screen protection for Asus Zenfone 9. Made from aluminum-silicone glass, and only 0.26mm thick, which ensures minimal interference with your touchscreen - while still offering 9H hardness rating! Most people prefer to buy multiple protectors at the time, unsurprisingly so as the screen is subject to heavy wear and tear. So here's a convenient package of two for a better price than buying two separately!
