This is the personal ball of Mark Caguioa. The one on the left side. As you can see it's bigger compared to the official Molten ball on the right side. It's also heavier than the normal ball. He bought it all the way from Eagle Rock in the United States.
Snow Badua said that when he tried dribbling Mark's ball, he felt its weight and he got tired faster in using it. He went back to hold the regular ball and he noticed that he can now dribble it in an easier way. That is probably why Mark has a great crossover dribble.
Mark uses this ball in his practices and he also shares this ball to his teamates.
