Crafted from premium top-layer vegetable-tanned cowhide, this piece is engineered to develop a unique patina over time. Measuring 11.5 x 8.5 cm with an exceptionally lean 0.3 cm profile, it provides substantial utility without disrupting the line of a tailored suit. The architectural interior features five card slots and a discrete zippered compartment for currency, balancing daily necessity with a refined, slender silhouette.
