Using this Harry Potter gift box is a breeze. First, take it out of the flat - packed state and gently unfold it. You can place your gifts or keepsakes inside easily. When closing, the magnetic strip on the lid will hold it shut securely. To make it look even nicer, tie the ribbon on the lid. As for maintenance, keep it in a dry place to prevent the card from getting damp. Avoid rough handling as it might damage the box. If it gets a little dirty, you can use a soft, dry cloth to gently wipe it clean.
