copper

The copper is the first bimetal signature yo-yo of Keiran Cooper — a celebrated competitor with victories at the European Yo-Yo Championship Open Division and the UK National Yo-Yo Championship.

As its name suggests, the copper takes a bold step forward with a rim design crafted from copper alloy. With a density greater than stainless steel, the copper rims provide massive rim weight in a compact frame, delivering a powerful balance of spin stability and control. The result is a yo-yo that holds steady, maintaining spin strength deep into long combos while still feeling surprisingly manageable on the string.

True to its name, the copper embraces the natural properties of its material. The rims are left raw and uncoated, allowing a natural oxide film to form over time. With play, the yo-yo develops a darker patina or even greenish hues, creating a unique look that evolves with you — every copper tells its own story.

This is a yo-yo built for champions, collectors, and players who value both performance and character.
