According to the�RIAJ, or�Recording Industry Association of Japan, an album needs to sell over 250,000 copies to be certified "Platinum" and below that is the "Gold" certification, meaning that an album needs to sell over 100,000 copies. The RIAJ website was recently updated showing that 'Dumb & Dumber' was certified 'Gold'.

Congratulations to iKON on this achievement!
