This Balenciaga piece on lanyard is meant to look like a passport with train tickets inside. In fact, it’s a calfskin wallet with a back pocket, 3 inner card slots, and a main compartment. It has a removable crossbody strap that’s about 21.6 inches. Can be worn around neck or crossbody. You can also clip this onto a larger back or into a belt loop. Excellent condition, hardly utilized. Men’s collection but certainly unisex.
