YoYoFactory String - MIX 10 Pack

Polyester Multicolor YoYo String, Bundle/100

YoYoFactory string is made of 100% polyester, unlike standard 100% cotton string. Polyester gives the string a smoother feel on your hands during tricks, it helps the string slide on the ball bearing of the yo-yo with ease for more complex string tricks, and it lasts much longer than classic cotton string.
