The screen protector by Northjo is a film, specially designed to protect the screen only from dust and superficial scratches. It does not protect the screen in case of a drop, as it is thin. It does not affect the screen's functionality. It is 2.5D, which means its perimeter has rounded edges for a smoother touch feel when using the screen. Useful for modern smartphones with curved screens. It is compatible with iPhone Air. See full description
