Using these toys is a lot of fun! First, take out each of the 5 transformable vehicles. You can play with them individually or start to combine them to form Kiramaizin. Try different combinations to get various modes of Kiramaizin. When handling the toys, be gentle as they have small parts that could break if roughly treated. To keep the toys in good condition, store them in a dry place away from direct sunlight. Avoid exposing them to extreme temperatures as this might damage the plastic. Also, make sure to keep the toys out of reach of very young children who might choke on the small parts.
