Welcome to the COROLYMPICS! We tested four different materials - iron, plastic, wood, and fine ceramics - to find out which could survive three grueling challenges and earn the title of "The Most Wear-Resistant Material." Watch and see which material emerges victorious! *In Japanese the onomatopoeic word "CORO-CORO" is used to represent the concept of rolling. The COROLYMPICS is a fictional competition which tests various materials as they roll through a series of obstacles.
