Really great wallet! I got the "vivid" color and it looks fantastic. Quality seems very nice, it smelled like leather when I opened it, and it's very lightweight. I just keep 1 card per slot so far as well as 1 card in the center and the cards fit well, nothing's gonna fall out. I think you can technically put 2 cards per a slot, I haven't tried that. I'm sure it would work but it may be difficult to get cards out. I've been carrying it around for a few weeks and overall I'm very happy with it!
