About
The Yoku YoYo Design edition of the Euler is a 2018 collaboration reissue of Ken Luo’s 2015 design, produced in China and distributed by Yo-Yo Store REWIND. Slightly smaller in diameter (52.62mm vs 53.3mm) and marginally heavier (63.9g vs 62.8g) than the original, the reissue brings the Euler design to a wider audience at $69.99 — a significant reduction from the original’s $229.99. Available in Black/Black Rim and four splash colorways: Yellow/Black/Purple, Orange/Blue/Black, Purple/Silver, and Light Blue/Yellow.
