The Hyper Yoyo Accel series features the innovative "Accel System," a patented technology (pending in both Japan and the US) that allows the yoyo to spin at high speed without being thrown. By pulling the string sharply while holding the yoyo, the system enables new tricks that were impossible with traditional yoyos. The "Accel Origin" is an entry-level model designed specifically for beginners. It excels in making basic tricks like "Accel Spin," "Trapeze," and "Walk the Dog" easy and enjoyable to learn. The "Accel Origin - Cosmo Purple" is a yoyo with a clear purple body featuring a design inspired by the cosmos.
