Using these tote bags is super easy! Just open the top and start putting your things inside. You can use them for shopping, going to the beach, or even as an everyday handbag. As for care, wipe them with a soft, dry cloth to keep them clean. Don't use harsh chemicals or abrasive materials, as they can damage the polyurethane. Also, be aware of the warning about the chemicals. Store them in a cool, dry place when not in use to maintain their shape and quality.
