Q
Keyboard protector: how thick is a cloth? I want this primarily to protect the laptop screen from the keyboard.
A
Approx. 1/2mm thick. Nice and thin and stretchy too. Well suited for this purpose :-) Anyone expecting a "thick" cloth will be disappointed, because these cloths are thin. But that's not a disadvantage, but an advantage, because it makes it easy to reach the edge of your glasses or behind your nose bridge to clean.
