Using these mecha is a lot of fun. First, take out each mecha from the gashapon set. You can play with them individually, or if you want to see the real magic, combine all 4 to form Lupinkaiser. Just match the connection parts carefully to get the perfect combination. When playing, make sure to handle them gently as they are small and can be easily damaged. To keep them in good condition, store them in a dry place away from direct sunlight. Avoid getting them wet. If they get dirty, you can use a soft, dry cloth to gently wipe them clean.
