Using your personalized Christmas lantern is a breeze. First, take out the lantern from the package. Insert the included batteries into the battery compartment according to the correct polarity. Once the batteries are in, switch on the lantern and watch it light up. For customizing, you can add your personal message, family name, or photos through the provided engraving service. When it comes to maintenance, keep the lantern in a dry place to prevent the plastic from getting damaged. If the lantern gets dirty, use a soft, dry cloth to gently wipe it. Avoid using harsh chemicals or abrasive materials as they can scratch the surface. Also, when the batteries run out, replace them with new ones of the same type. Enjoy your lantern for many holidays to come!
