To use this product, first, take the Bitty POP! Shiro out of the hard acrylic display case. Then, place him in the Bitty POP! Bitty Bot Voltron. When you're not using it, you can put the figure back in the case and use the detachable bottom lid as a base for display. Please note that this is a choking hazard due to its small size, so keep it away from children under 3 years old. To maintain it, just use a soft cloth to gently wipe the vinyl figures and the acrylic case if they get dirty.
