Apple Key Caps

As far as we know, all 2010 range MacBook Air 11-inch and 13-inch use the type-J clip.

Please note that the 11-inch and some 13-inch 2010 MacBook Airs did not have illuminated keyboards and the keycaps are made of opaque black plastic with the character printed in a silver paint. Although they are physically interchangeable with later MacBook Air and Retina MacBook Pro type-J keycaps, they are cosmetically different and do not allow the keyboard backlighting on those machines to shine through.
