YoYoStringLab makes some of the best string on the market and their latest string was used to win the 2018 World Yo-yo Contest! YoYo String Lab PLUTONIUM!

Plutonium is soft on the hands but also really good for whips and lacerations. It has a tighter wind than Venom and is slightly thicker for a completely new feel in play. It has the perfect balance for competitive and casual throwing.
