Passport wallets and cases provide a way to keep important travel documents together in a safe, organized and convenient manner. Multiple slots can hold an array of items including a passport, driver's license, medical card, insurance card, airline tickets, boarding pass, itinerary, credit cards, receipts, traveler's checks and currency. Additional features like a pen slot and calculator will also come in handy. Travel wallets generally have a zipper, Velcro or clasp closure to keep contents secure, clean and dry. Most passport holders fold in half like a book and are slim enough to be tucked inside a handbag, shirt pocket or coat. There are even styles that can be worn around the neck for extra security and ease. Travelers can select passport cases and wallets that match their luggage, duffel or tote bag or select a unique color, fabric or style. Leather and suede materials are comfortable, durable and soft to the touch. Other quality materials include nylon, polyester and canvas. In need of a travel document holder?
