Great find, JS.
Remember a few years ago, when everyone needed a case for their PRS-950 and snapped up M-Edge Executive Jackets for the Kindle 2 while they were drastically marked down? That sale was so good that I also picked up a leather pocket case in navy, thinking I'd find a use for it eventually. Well, that case turns out to fit the Aura exceptionally well, and as we all know, navy compliments brown.
It's a bit like
this Saddleback design, only with a leather belt piece that fastens the Aura in, quilt-textured leather (which I quite like), and a far, far lower price tag.
