To use this Harry Potter Light - up Hogwarts Kit, start by taking out all the flat parts from the box. Carefully assemble them one by one to build the Hogwarts castle. Once the basic structure is ready, add the 6 included LED lights. This will give the model a magical glow, just like Hogwarts at night. Remember, this kit is for kids aged 8 and up. Keep it away from children under 36 months because there are small parts that can be a choking risk. When you're done playing, store the kit in a dry place to keep all the parts in good condition. If any parts get dirty, you can gently wipe them with a soft, dry cloth.
