Fire poi with minimal amount of metal parts. They are made of 100% Kevlar weaved rope without stiff core. Core is from kevlar. Each burner is made from kevlar rope tightly bound in a monkey fist knot giving you excellent burn times and flame size. Due to the spherical nature of monkey fists you also get a different shaped flame. As the poi are spun the round flames leave a trail behind them resulting in a beautiful comet-like effect. Lifetime about 200 burns.
