The BookBook has a hard shell and a rigid spine to keep your MacBook from being crushed, and is lined with soft fabric to keep it from being scratched. Twelve South also plays up the fact that by disguising your laptop as a beat up old book, you make it less likely to be stolen. Because who wants to steal an old book? Besides these guys.
The leather cases are hand-distressed, so each tome is unique, and the cases have two zippers that are disguised as bookmarks to complete the illusion. These books look so authentic that you might even fool yourself into thinking that you've been reading an old hardcover book.
