Well in the running for ultimate minimal man-fold, the Obtainium Wallet is sleek and no-nonsense, a flip open affair that holds cards at the ready with its unique slip-under-strap system. It’s crafted from aircraft-grade aluminum, hardcoated for durability, low friction and sexy feel (with tapered edges inside and out to promote easy sliding), and it blocks RFID scanning. Holds 10 cards (or eight cards and some cash). Comes in Platinum Grey, Gold Bar, and Military Olive. $199.
