The go-to wallet for minimalists Wally Micro is a slim card sleeve with a few tricks up its, well, sleeve. It’s surprisingly accommodating as a front-pocket wallet or business card holder, flexing to secure a varying stack of up to 10 cards revealed with our signature pull-tab. So, what's the trick? Wally Micro is reversible. That's right—like Clark Kent ducking into a phone booth to remove his glasses, threading the tab through gets you two stylish colors in one card-carrying minimalist wallet.
