The manilla envelope stunt pulled with the introduction of the MacBook Air is destined to go down as the stuff of marketing legend. Now, at least one happy Swede has his piece of consumer history with the receipt of the ManillaMac AirMail sleeve. It arrived with a spare red string and button and the added touch of his name hand written on the shipping label -- nice. According to Michael, his "high quality" sleeve fits the MBA "perfectly" and features "very good" stitching with white cotton innards which should keep his MBA looking just as glossy clean his new sleeve.
