These cool graffiti quilted bags are super easy to use. Just throw in your daily essentials like phone, wallet, and keys. You can carry them by hand using the chain belt or sling it over your shoulder for a more casual look. When it comes to maintenance, use a soft, dry cloth to wipe off any dirt or dust. Avoid getting the bag wet as it may damage the polyurethane material. Since the bag contains chemicals like cadmium, lead, and nickel, don't let it come in direct contact with your skin for long periods. If you have any concerns about the chemicals, refer to www.P65Warnings.ca.gov for more information.
