About
The F3S-2 is YoyoFormula’s flagship LED yo-yo — an ultrawide POM construction with two USB-rechargeable LED circuit boards. At 84g and 69mm in both diameter and width, the extreme dimensions maximize trick visibility and string exposure during light-up performances. The rechargeable USB system replaces battery-dependent LED designs. Comes with a USB charger, extra strings, and a counterweight. Replacement LED circuit boards are sold separately.
