These tote bags are super easy to use. Just open the top and start filling it with your daily essentials like your phone, wallet, keys, and makeup. When you're going out for a shopping spree or a day at the beach, these bags will hold all your stuff. As for maintenance, wipe them down with a damp cloth regularly to keep them clean. Avoid exposing them to sharp objects that could scratch the polyurethane surface. Also, keep them away from extreme heat as it might damage the material. And remember, due to the chemicals they contain, don't let children chew or play roughly with the bags.
