Kui
Light-up metal yo-yo, a collaboration with Luo Yicheng
A collaboration between YoYoFactory and Chinese pro Luo Yicheng, who placed fourth at the 2008 World Yo-Yo Contest, Kui is a metal yo-yo with built-in LEDs under polycarbonate side caps. The lights switch on when it's thrown, and the caps sit slightly proud of the body so the light shows during play; they also work as fingerspin caps. Released in July 2018.
The LEDs run on replaceable CR1220 batteries, reached by unlocking the caps with the included hex tool. A USB blacklight strip comes in the box to make fluorescent string glow. It ships with a Center Trac bearing and 19mm response pads.
We ship worldwide from Sweden with both traceable and non-traceable options based on destination.
Packages shipped to the US have import duties and tariffs pre-paid by us, nothing to pay on delivery.
