These bags are super easy to use. Just open the bag and put in your daily essentials like your phone, wallet, keys, and makeup. You can carry them by hand or over your shoulder. When it comes to maintenance, use a soft cloth to wipe off any dirt or dust. Avoid using harsh chemicals as they might damage the polyurethane and mixed metal. Also, keep in mind the California Proposition 65 warning. Don't let children play with the bag in a way that they might be exposed to the harmful chemicals. Store the bag in a cool, dry place when not in use to keep it in good condition.
