The K3 Aurora-P is the 3rd release in the plastic 'K' series line-up. It features one of the most unique shapes we have seen in many years. Each half is a 'bowl' shape, making it incredibly rounded, and also removes any sharp edges to make it more comfortable for beginning players. The K3 also features a fingerspin dimple, and due to the curved, bowl shape of each of the yo-yo halves, makes learning and performing tricks like the DNA much easier. It's made from Acrylonnitrile Butadience Styrene (ABS) plastic, which is tougher than any other plastic used for making yo-yos, making it incredibly durable. And comes responsive out of the box, with an unresponsive upgrade kit included.
