I got this wallet a few days ago. It had the break-in period others mentioned, lengthened a bit to suit the amount of cards and cash you're carrying around. It's been 2 days and mine seems to have stretched just right. My last double fold leather wallet was too thick. After searching the web and Revain I settled on this wallet based on the material, price, number of slots and other reviews. If you have more cards, you may need a duplicate version. I have 3 cards in one pocket, 4 in the other and 2-8 bills in the middle. I really like it! It's so thin and comfortable that I naturally carried it in my front pocket even though it wasn't meant to be carried in a wallet. If anything changes drastically I'll update my review, but for now this is the best wallet decision I've ever made. That's not to say there aren't other minimalist wallets made out of incredible materials, because I've found quite a few. Explore for fun. For now, this is simply the best bang for your buck.
