Using your new men's croissant bag is a breeze. Unzip the top to access the internal compartments. You can keep your ID in the ID bag, your phone in the phone bag, and other small items in the zipper pocket. When carrying it, make sure not to overstuff it to maintain its anti - seismic function. To keep it in good condition, avoid getting it wet. If it gets dirty, use a soft, dry cloth to gently wipe the surface. Store it in a cool, dry place when not in use.
