Using the Mini Barbieland Pop Reveal Barbie Doll is super easy. First, unscrew the lid of the mini drink cup. Then, take the straw and poke the sensory compound inside for some squishy fun. Once you're done with that, remove the compound, and there's your cute 1.5 - inch Barbie mini doll! The doll can stand on the heart - shaped base, and you can fit this base into Mini BarbieLand playsets (which you need to buy separately). You can also use the mini drink cup to keep the doll safe when you're not playing with it. As for maintenance, keep the doll away from sharp objects to avoid any damage. If it gets dirty, you can gently wipe it with a soft, damp cloth. Remember, these dolls are for fans aged 4 and above, and since they're sold separately, availability might change, so grab them while you can! Also, don't be surprised if the colors and decorations of the dolls vary from what you see in pictures.
