The 3.5 inch LCD Screen Protector with Microfiber Cloth (3 Pack) from Giottos is made of tempered optical glass from Schott Germany. The 12 AR Coatings on each side eliminate glare and light reflections on the LCD as well as aberrations, residual images and ghost images from the CCD. Giottos AEGIS completely protects the LCD from abrasions, scratches, impact, dust and moisture. The top layer on each side repels dust and moisture to aid in keeping the Aegis clean! The Aegis adheres to the frame around the LCD and is not in direct contact with the LCD screen. The Aegis is easily removed by heating it with a hair dryer!
