The newest collectible from Tech 4 Kids, Nitro Grinders, has made its global debut in Canada, where it will be sold exclusively this summer. Kids use their fingers to make Nitro Grinders jump, spin, and grind over obstacles without falling over. Series 1 has 56 characters to collect, including special sets with customizable wheels and ramps. Nitro Grinders will be available in the U.S. this December.
