Ensure your new laptop goes undetected by thieves with the BookBook Vol. 2 Concealing MacBook Sleeve. As another chapter in the series, this sleeve leads a double life. On the exterior, the BookBook Vol. 2 looks just like a classic book you’d find on a bookshelf. The spine has all the characteristics of an encyclopedia while the front and back look like generic book covers. However, the inside provides protection for your laptop. Compatible with the 12, 13, and 15-inch MacBook editions, the BookBook Vol. 2 has elastic bands so you don’t even need to remove it from the case. This makes it easy to get back into your work. In addition, the BookBook Vol. 2 has a hidden folio section to store your documents.
