Twelve South's vintage book looking case for the MacBook Air protects your expensive investment using the two rigid hardback covers while the inside is padded and lined with soft, velvety cushions. Sounds to me like a good story. The thin and light BookBook is designed exclusively for the unibody 2010 MacBook Air and is handmade using genuine leather that is hand distressed for the ultimate vintage feeling. No two BookBook cases are exactly alike. If you fancy yourself one of these vintage leather book cases for your MacBook Air, $79.95 will get you a little closer to a book you otherwise would have never touched.
