At last, your claims of knowing New York’s subway system “like the back of your hand” will be more than just boasting (OK, lying).

The NYC Metro Cuff is an ” über urban matte metal cuff” capable of guiding you a la treasure map through NYC’s intricate train system. No one will take you for a tourist as you compulsively check your “watch,” studying the embossed map fervently while inching away from yet another passenger who dually loves garlic and despises deodorant. Order yours for $US25 shipped. [design hype via Gearfuse]
