Maximum protection with unobtrusive optics The display cover of armoured glass offers effective protection against scratches, dirt and shocks. At the same time, it is feather-light and only 0.4 mm thin, so it's a very good choice for those who don't want to do without additional protection but don't want to spoil their device with a clunky case. The touchscreen functionality is not affected in any way, as there is no space between the display and the bullet-proof glass screen. A grease-repellent coating prevents annoying fingerprints and makes cleaning easier.
