Marvêlles Tempered Glass is made of Japanese Asahi glass, this hardened with a superior hardness of 9H. This means that the procedure begins with the glass first heating up to 370 degrees Celsius. The heat is increased up to 410 Celsius where the glass is compressed for 3 hours, giving it toughness, hardness and composition that ensures that the glass passes the sample where a metal ball of 35g falls from a 0.7 meter height straight on the glass. You then cut the glass with a special C laser around the curved edges to ensure that the glass fits perfectly on the display and leaves no room for air bubbles. 3 mm thick and a smooth Oleophobic coating counteracts dirt and fingerprints while retaining the same sensitive touch as the original screen. Japanic Asahi glass is the most scratch-resistant and durable screen protector on the market and it will ensure that your screen has perfect conditions for a long time. This glass fits the Iphone 13 Mini and is the 3D model.
