To use this Barbie Pop Reveal Chelsea Doll, first, take the straw - like piece and pop the top of the juice box packaging. You'll smell one of the four fruit scents right away. Start unboxing to find the scented Chelsea doll, mystery bags, and the ice cube. Pop the ice cube gently to discover the roller skates. You can reuse the ice cube for more pop - reveal fun. Open the mystery bags to get the skirt and the squishy pet. Keep an eye on Chelsea's face to see the color - change transformation. Remember, the dolls can't stand on their own, so you might want to display them in a way that supports them. As for maintenance, keep the doll and its accessories away from sharp objects to avoid damage. Also, store them in a dry place to prevent any odor or color changes. This product is suitable for kids aged 3 and up, so adult supervision might be needed for younger children during the unboxing process.
