To use this wallet, simply open it up and place your cards, cash, and other small items in the 5 internal compartments. You can keep frequently used items like your ID or transit card in the external zipped pocket for quick access. When it gets dirty, just wipe it clean with a damp cloth. Avoid using harsh chemicals or abrasive materials as they may damage the polyester material. Also, don't overstuff the wallet to prevent it from losing its shape.
