MiNGFi 0.1mm Keyboard Protective Case / Cover for MacBook Pro 13 "15" 17 "and Air 13" EU / ISO Keyboard Layout Silicone Skin - Transparent / Slimline (Electronics)
Protects the keyboard from dust and liquids, but changes a little too touching the keyboard. This is still quite usable with a little practice, but it is annoying.
