Designed to protect from dust, dirt, and spills, the ClearSkin keyboard cover has been perfectly engineered to fit your MacBook, MacBook Air, or MacBook Pro (Unibody)...and allow the backlit keys to shine through. The ClearSkin keyboard cover is the thinnest, clearest cover we have ever made. And now, it also fits the Apple Ultra-Thin Wireless Keyboard! The ClearSkin keyboard cover is made of a 0.1mm advanced space-age plastic, so clear that it is almost invisible when put on the keyboard...and because it is so thin, you can hardly notice it when typing.
