Using this product is super easy. First, unscrew the lid on the mini drink cup. Then, take the straw and poke the sensory compound inside for some squishy fun. After that, remove the compound to find your cute 1.5 - inch Barbie mini doll. The doll can stand on its heart - shaped base and fit into Mini BarbieLand playsets (you need to buy the playsets separately). You can use the mini drink cup to store the doll when you're not playing with it. When it comes to maintenance, keep the doll and the cup away from sharp objects to avoid damage. Also, try to store them in a dry place. Remember, the dolls are sold separately, so availability might vary, and the colours and decorations on the dolls may not be exactly the same.
