Using your new denim backpack is a breeze. Just open the double pockets in front to easily store your daily essentials like your phone, wallet, or keys. You can carry it on your back for hands - free movement during your daily commute, school days, or weekend outings. As for maintenance, use a soft brush to gently clean off dirt. If it gets wet, let it air dry naturally. Be careful not to overstuff the backpack as it may lose its shape. Also, keep in mind the California Proposition 65 warning about the chemicals in the product, and avoid direct skin contact with the metal parts for long periods.
