Using your personalized Christmas lantern is easy. First, open the lantern and insert the included batteries. Then, place the lantern in your desired spot, whether it's on a table, mantel, or window sill. To add a personal touch, you can use the custom engraving option to put a message, family name, or photo. When it comes to maintenance, keep the lantern away from water as it's made of plastic. If it gets dirty, you can gently wipe it with a dry cloth. Don't expose the lantern to direct sunlight for long periods to avoid any damage to the print. Also, when the batteries run out, simply replace them with new ones to keep the lantern shining bright throughout the holiday season.
