This beautiful, handcrafted leather case from Leathinity fits the 11″ MacBook Air, but they do have similar cases sized to fit the 13″ MacBook Pro and Air. These cases are handmade from genuine cowhide (1.3-1.4mm thick). The cases are available in the brown shown in the photo, dark brown, and black. In addition to the flap with buckle-and-peg closure shown above, a simple open top with strap-and-peg closure version is available. Depending on the style and size, cases are priced from about $70 to $101. Leathinity is based in Hong Kong, but they sell through Etsy and ship world-wide.
