Premium glass mouse pad The ultimate in performance and durability, with a top layer of super-strong aluminium silicate glass and a unique surface pattern for fast glide and good stopping, and a bottom layer of high-density silicone for a secure grip. Aluminium silicate glass Aluminosilicate glass, also known as Gorilla glass, is a type of chemically tempered glass used in a variety of applications, such as mobile, tablet and laptop screens. It is known for its high durability and resistance to scratches and cracks. It is produced by an ion exchange process in which the surface of the glass is bombarded with ions of a specific element, e.g. potassium, which makes the surface of the glass harder and more resistant. Basically, this is a super-hard glass. Slip resistance and stability at its best The fully moulded, high-density silicone rubber design provides maximum grip on surfaces, ensuring stability and reducing the risk of slipping. Because the entire underside is covered, not just the corners, it provides extra grip and prevents give in the centre.
