SuperYo SpinBoss YoYo String (5-pack), circa late 1990s–2000s.
Retail pack of five 100% cotton yo-yo strings marketed as "works on all yoyos." The strings are multi-color twist and are pre-tied on one end. The bold, comic-style "SUPERYO!" masthead and bright starburst design match SuperYo’s house look from the Renegade/Hyper-Spin era.
It's interesting to note that 100% cotton string remained the standard yo-yo string option even as polyester began to gain popularity with some players, making this an illustrative example of mass-market yo-yo upkeep from the period.
