We’ve gone to great lengths to streamline the junk in our pocket. We tried just about every “minimalist” wallet, we flirted with messenger bags and we had a nightmare in which we adopted a fanny pack. Still, Killspencer nailed it with their iPhone Card Carrier. Now back and better than ever, the Killspencer iPhone Card Carrier 2.0 is set to store four of your cards right on the back of your iPhone. Made with leather or nylon and a slim piece of wood, every slim card carrier sports a thumb port for easy access to your plastic. Available in a few different styles (camel pebbled leather, camo and more) it’s a smart and sleek wallet option.
