How to use: First, take out the playset and set up the Room of Requirement. Place the Dueling Dummy, Hermione, Ron, and their Patronuses in the room. You can then use your imagination to recreate scenes from the Harry Potter movies, like conjuring Patronuses and dueling. To transform it into the Room of Hidden Things, just re - arrange the elements. Attention: Keep small parts away from children under 5 to avoid choking hazards. Maintenance: Wipe the figures and playset with a dry cloth if they get dirty. Don't use harsh chemicals as they may damage the colors and materials.
