Three stacked credit card slots, stitched with the center slot riding higher than the outer two to allow easier access to the 'middle cards,' without having to unpack the whole bunch.

Laser cut from a single piece of Horween horsefront leather (thin, strong, low stretch, durable), folded and hand stitched with burnished edges.
