Mattel, the American toy manufacturing company behind the famous 'Barbie' collection, has released teasers of their collaboration project with BTS. 

On Monday, Mattel unveiled a photo showing the silhouettes of the K-pop idols. The caption stated, "No more dreaming. Something big's coming."

A day later, Mattel released another teaser - this time, a close-up shot of a doll's dimple. "You can call him an artist, you can call him an idol...," tweeted Mattel.

And today, the teaser showed a part of the dolls' outfits, which resembles the outfit from "IDOL."

The 11.5-inch dolls are scheduled to release in September. Meanwhile, BTS announced they'll be dropping the new album 'Map of the Soul: Persona' on April 12.
