A great, glowing yo-yo ball. Thread your fingers through the string at the end of the ball and pretend you have a yo-yo in your hand by tapping the ball into your palm. As soon as the ball hits your hand, it lights up in red, blue, and white thanks to the built-in LED. These little balls will be a hit with children at a birthday party. A gift that will be well received at any event. The Special Day team has tested the toy and found it to be good.
