Using this neck wallet is a breeze. Just put your passport, credit cards, and money in the main pocket and use the mesh divider to keep things organized. Adjust the neck strap to a comfortable length and use the strap keeper to hold it in place. When traveling, wear it under your clothes for added security. As for care, you can gently hand - wash it with mild detergent and let it air dry. Avoid using harsh chemicals or putting it in the dryer. Keep it away from sharp objects to prevent tears. If you're not using it for a long time, store it in a cool, dry place.
