How to use: First, enjoy the unboxing fun of each type of doll. For Color Reveal dolls, use water to reveal their colors. For Cutie Reveal dolls, take off the cover to see the cute costumes and tiny pets. For Pop Reveal dolls, have a sensory experience with the squishy compound. Then, place the 1.5 - inch dolls on their heart - shaped bases. You can use them with Mini BarbieLand playsets (sold separately) to create your own mini world. The mini packaging tubes can be used to store the dolls when not in use. Attention: Since colors and decorations may vary, don't be disappointed if your set looks a bit different from others. Also, keep the squishy compound away from small children who might put it in their mouths. Maintenance: To keep the dolls clean, you can gently wipe them with a soft cloth. Store them in a dry place to prevent damage.
