25 Pack YoYoFactory 100% Polyester Yo-Yo Replacement Strings. Having spare string on hand is an essential part of Yo-Yoing. Like any sport, your equipment needs maintenance. YoYoFactory Modern Performance 100% Polyester string is designed to last longer and play smoother than traditional cotton string.
YoYo Shop also have 10 packs of YoYoFactory 100% Polyester Strings available.
NOTE: sometimes we may package these strings in our own bags, that will not look like the pictured packet - but the strings themselves are the same!
