Easecase bespoke wallet cases
Haven't seen these posted in the Galaxy Nexus forums yet! This is a Hong Kong based store (I'm not affiliated with them in any way btw, I'm from the UK) who make cases to order, and when I was shown them by a friend a while back and I fell in love. You get to customise just about everything about the wallet-style cases, from what kind of seal you want, to the interior material, to the imprinted text.
However, looking at their GNote cases, I really want an exposed screen. Maybe if enough of us email them about it then they'll make them like that, too
but for now, I like the E6 with credit card slots and a cash section!
