Twelve South 12-1001 BookBook, Hardback Leather Case for 13-inch MacBook Pro (Black) Slip your Mac inside the velvety soft, padded interior. Zip it closed and your baby is nestled between two tough, rigid leather hardback covers for a solid level of impact absorbing protection. Each BookBook is brought to life with hand craftsmanship and distressing, ensuring no two are exactly alike. From dual zippers with leather pulls, that at first glance look like bookmarks, to the sturdy reinforced hardback covers, BookBook is a vintage work of art built to protect modern day Macs. One of the neatest features of BookBook is the stealthy security it delivers. Tucked inside BookBook, no one will ever see your MacBook Pro , even when it's right under their nose.
