The Leather Hybrid World Bi-fold Wallet has the shape of a bi-fold wallet, but is the size of a passport wallet. It's one of the few men's wallets on the market with a zipper compartment, plus it's tall, thin and spacious. Whether you're a world traveler that carries money from all over the world or consider a trip beyond your city's limits as a grand expedition, the World Wallet has the features you need to keep everything organized without being squished. There's even a zippered coin pocket on the outside for easy access to change and small items. Besides being technically perfect in nearly every way (modest, we know), the men's leather wallet with zipper is also super-interesting. It measures almost a perfect 4 inches square, which is a cool fact you can bring up in conversations with strangers from all over the world. While you're chatting about your black leather wallet with zip coin pocket, be sure to point out that it's thin and light, but carries as much stuff as a pack mule.
