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.

KARATZ’s Blue Lock collection is available for purchase here from the official website. The collaboration follows its jewelry collaboration with The Apothecary Diaries earlier this year.

The Blue Lock anime adapts the manga of the same name by Muneyuki Kaneshiro (story) and Yusuke Nomura (art). Crunchyroll streams both seasons, describing the series:
Japan’s desire for World Cup glory leads the Japanese Football Association to launch a new rigorous training program to find the national team’s next striker. Three hundred high school players are pitted against each other for the position, but only one will come out on top. Who among them will be the striker to usher in a new era of Japanese soccer?
