These tote bags are super easy to use. Just open the top and put your essentials inside, like your phone, wallet, and keys. When you're out and about, they're great for carrying your daily items. As for maintenance, use a soft, damp cloth to gently wipe the surface of the bag if it gets dirty. Avoid using harsh chemicals as they can damage the polyurethane material. Also, don't forget about the warning. Since the product can expose you to harmful chemicals, be careful when handling it and keep it away from children and pregnant women.
