GLAS.t is made to protect the LCD from damage and scratches with specially processed glass that has been reinforced to increase shock absorbency. The GLAS.t is 0.4mm thick and made with chemically treated, transparent tempered glass. The surface of the GLAS.t has a hardness of 8-9H, three times stronger than regular PET film. The Spigen Glas.t works well, and has proven useful against knife scratches as well as the normal wear and tear. But it does really stand out against heavy-duty attacks on your iPad display.
I high recommend it and you can order yours here
