I've become pretty minimalistic with my wallet. I currently use a leather credit card holder (similar to this), that has two slots on each side. I'm tempted to try out either the Jimi wallet or the JimiX, mainly since I keep seeing references to them. When I first read the specs, I was thinking 9/16" is pretty thick, but that's about how thick my wallet is with everything in it. I am curious as to how many cards would fit in it . . .
