YoYoFactory 10 Pack Professional 100% Polyester Yo-Yo Strings - Durable Performance for Competition & Trick Play

10 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.

NOTE: these strings are best for those with bearings.  For fixed axle yoyos 50/50 Polyester/Cotton string is better.
