About
The arc is RiHara’s debut model, initially released under the brand’s original name, 7yoyodesign. The company rebranded to RiHara after the first arc units shipped. Featuring Zhang Wenlin’s signature curves-based, minimalist profile, the arc established the design language that would carry through the brand’s entire catalog. Early units with a green logo and silver blasted finish are among the most sought-after pieces in the modern Chinese yo-yo collector community. TopYo later produced a remake of the arc. Full specifications are not publicly documented in surviving sources.
