The AirMail notebook sleeve for Apple’s new MacBook Air is handmade out of durable upholstery-grade vinyl, and lined with fuzzy, soft fleece. All AirMail sleeves have the same dimensions as standard interoffice manila envelopes, which will serve to remind you — and everyone around you — that your new MacBook Air really is the world’s thinnest laptop.

The AirMail is the brainchild of Jona Bechtolt and Claire L. Evans, two Apple geeks who decided to take Steve Jobs up on his idea that the MacBook Air can fit inside a standard manila envelope. (Besides, they wanted a cool case to show off their new MacBook Air notebooks!)

AirMail laptop cases are lined with thick fleece, which will protect your laptop from any cosmetic damage and smudges, and keep it safe from bumps in daily use.

AirMail is available for pre-order now for US$29.95 and you can expect to receive it via USPS Priority Mail by the time you get your MacBook Air.
