The Koi SS makes an absolutely beautiful return in rainbow fashion! 
Don’t miss this Limited Edition Rainbow Acid of the SS Koi, along with the Rainbow, and Yellow with Rainbow Splash editions! The SS Koi yoyo marks yoyofriends’ entry into the realm of D-bearing yoyos.
The smaller D bearing enhances power and spin speed, aligning perfectly with their performance-driven culture. The SS Koi delivers a powerful, stable, and flowy experience, blending performance, fun, and specialty within its organic and undersized form.
