Spigen's tempered glass is a hardened glass, specially made to cover and protect your mobile phone's screen from scratches and other damage. It does not affect the operation of the screen. In the event of a fall of the mobile phone, it does not guarantee that the screen will not break with it, however it is an additional protection. It is 2.5D, which means that its perimeter has rounded edges for a softer touch feeling when using the screen. Useful for modern smartphones that have curved screens. It is compatible with the Galaxy S24.
