Designed exclusively for MacBook Air, BookBook is a totally unique case for the thinnest of MacBooks. Weighing as little as 13.5 ounces with an ultra-thin profile, this handmade, genuine leather case offers heavy duty protection. Two hardback covers, reinforced corners and a tough spine offer solid impact protection. The inside of the case is lined with a velvety soft, chocolate brown, padded interior for added protection.
