The Spinner Shark Drifting Kneeboard is hands-down 5-star fun for kids! Enjoy watching your children burst out laughing as they swirl into 360-degree fishtail spins and tailwhips. The ultra-smooth casters mounted to the sticky pu wheels allow the rider to drift to the left and right while maintaining maximum control. As an added bonus, the Spinner Shark has an innovative dual handbrake that allows children to gain speed and slow down while never loosing braking ability. To top it all off the Spinner Shark is built on top of a solid heavy-duty steel frame that will stand up to anything your kids throw at it.
