Using this men's messenger bag is a breeze. Open the flap and use the zipper to access the main compartment. The interior pockets are great for organizing your essentials like your phone, cards, and small items. For business use, keep your documents neatly in the main compartment. When it comes to maintenance, use a soft, dry cloth to wipe off any dust or dirt regularly. Avoid exposing the bag to excessive moisture or direct sunlight, as this can damage the PU leather. Also, be careful not to overstuff the bag to maintain its shape. With proper care, this bag will serve you well for a long time.
