CORTIS has achieved a double million-seller with its debut album.

According to the latest data from the Circle Chart, the group's debut album COLOR OUTSIDE THE LINES has surpassed 2 million copies in cumulative sales.

The album was originally released in September last year and has shown remarkable longevity. It exceeded 500,000 copies about a year after release, then crossed the 1 million mark two months later in November.

The album's long-running popularity has also been reflected on the U.S. charts. COLOR OUTSIDE THE LINES has remained on major Billboard album rankings, including the World Albums chart, for 25 consecutive weeks.

It also climbed the Billboard Top Album Sales chart for a second week, jumping nine spots from the previous week to land at No. 24. The momentum has been supported by the group's expanding global activities, including appearances at NBA events.

Meanwhile, CORTIS is currently preparing for a comeback targeted for next month.
