How to use: First, find some cold water and dip the sponge on the star - shaped wand of the Barbie fairy doll into it. Then, swipe the doll's wings to make the hearts on them change from pink to red. Wave the wet wand over the doll's bodice to see the ombre effect. If you want to change the colours back, use warm water. Notice: This toy is not suitable for children under 36 months because it has small parts. Maintenance: After playing, dry the doll and its accessories with a soft cloth to keep them in good condition. Store it in a dry place to avoid damage.
