YJYOYO teams up with world-class competitor Nam Dong-Hun to bring you the LM—a high-performance monometal evolution of the acclaimed Radiance, designed to match his electrifying speed and explosive style.

The name LM, short for lumen, draws inspiration from the unit of light—perfectly symbolizing Nam Dong-Hun’s intense stage presence, lightning-fast combos, and brilliant control under pressure. This yo-yo is all about fast, fluid movement, and commanding performance on the competitive stage. The LM features the same innovative Tilt Pad System found in the Radiance. This unique response design is optimized for today’s thicker strings, delivering reliable binds while reducing unexpected returns during fast-paced or high-risk tricks. It keeps up with every move, no matter how fast or technical your style.

With its lightweight feel, yet stable design and a more accessible price point, the LM brings professional-level performance to a wider range of players. Whether you're chasing blazing speed, smooth control, or just want a mono-metal that shines on stage—LM is ready to light the way.
