These tote bags are super easy to use. Just open the top and put in your daily essentials like your phone, wallet, and keys. When carrying, you can hold the handles in your hand or throw it over your shoulder. As for care, use a soft, dry cloth to wipe off any dust or dirt. Avoid getting the bags wet for long periods as it might damage the faux leather. Also, keep them away from sharp objects to prevent scratches. Remember, due to the warning about chemicals, don't let children chew on the bags.
