Using these crossbody bags is easy. Just put your essentials inside and sling it over your shoulder. When you're out and about, it's a great way to keep your hands free. For cleaning, use a damp cloth to wipe the surface gently. Avoid using harsh chemicals as they may damage the nylon material. Also, don't forget about the California warning - be aware of the potential exposure to harmful chemicals. Keep these bags in a dry place when not in use to prevent any moisture damage.
