Glass from the company Volte-Tel for protecting the tablet screen from scratches, damages, and fingerprints. It is easily applied and does not affect the touch function. It has adhesive on its entire surface, unlike edge glue glasses that only have adhesive on their perimeter. This helps in better application and smooth touch screen operation. It also prevents dust from passing underneath, which can happen with edge glue when the perimeter adhesive wears off. It is 2.5D, which means that its perimeter has rounded edges for a smoother touch experience when using the screen. Useful for modern smartphones with curved screens. Compatible with iPad Air 2024 13".
