Blue Lock and KARATZ Team Up for New Jewerly Collaboration

By Josh PiedraJuly 29, 2025

BEENOS Inc. announced the global release of a limited-edition jewelry collection born from a collaboration between Blue Lock, the hit soccer anime, and KARATZ, a fine jewelry brand specializing in ethically sourced gemstones. The exclusive line is available to international fans through Buyee’s cross-border shopping service.

The 30-piece collection features three distinctive jewelry styles—two rings and an ear cuff—each infused with Blue Lock’s signature design motifs. Every item comes in ten unique variations, with colored gemstones chosen to reflect the personality and spirit of 10 of the anime’s characters. The use of blue sapphire and blue chalcedony across the line pays homage to the anime’s base palette.

Each item includes a premium jewelry box and a collectible illustration card, making these elegant pieces a must-have for fans who want to wear their favorite striker’s ego with pride.
