Using these Zyuohger mini transforming cubes is super easy. Just hold the cube and gently transform it into the corresponding figure. When you're done playing, transform them back into cubes for easy storage. Keep these cubes away from small children as they might pose a choking hazard. To maintain them, simply wipe them with a dry cloth if they get dirty. Don't expose them to extreme heat or moisture, as this could damage the figures.
