Electro Spinstix are light up juggle sticks, more commonly known as Devil Sticks. The larger, thicker stick with weighted ends is the baton. It contains hidden LEDs that can be set to flash through different sequences of colors, enhancing the overall effect of the display. A special sticky grip finish makes for fast learning and easier play. An instructional CD with over 40 short video lessons is included along with the required four CR2032 batteries.
