From beginner to pro the Yoyo King Mesmerize Yo-Yo is perfect to easily perform string tricks like the Trapeze, Split the Atom, Braintwister, or the Double or Nothing. Mesmerize your friends with the hypnotic pattern that looks really cool when it spins. It's one of the best yoyos for kids, or for a yoyo professional, and will become one of your favorite yo yos of all times. Tough, solid polycarbonate plastic is the same material used for bulletproof glass and as strong as metal. The Mesmerize yo-yo has a silicone response system and a narrow bearing so it is responsive and wakes up when you tug on the string. With the narrow bearing that comes installed on the Mesmerize, you get the perfect amount of responsiveness for all of your standard yoyo tricks. This means that you or a kid can tug on the string and make the yoyo wake up and come back to your hand, like a traditional yoyo skill toy should operate.
