After years of producing cases for the iPhone and iPad, Apple finally got into the laptop sleeve business late last year. The leather case sported “high-quality European leather with a soft microfiber lining,” along with the obligatory Apple logo and “designed by Apple in California” guarantee. For whatever reason, however, it was a MacBook-only proposition.

That changes today, however. Today’s new MacBook Pros mean new MacBook Pro sleeves. They’re essentially the same leather/microfiber combo as the standard MacBooks, albeit altered to fit the larger notebooks’ footprint.
