Our BirthdayCOLORING BOOK

OURBIRTHDAY – Our Birthday (COLORING BOOK) is one physical edition of the 1st single album by OURBIRTHDAY, released on August 19, 2026. This is a physical CD: disc, photobook and cards in one box.

The box declared by the distributor holds 2 sticker sheets, one disc, and one box. It also holds Coloring Book, as declared by the distributor.

No POB is listed for this version in pocabase. A POB (preorder benefit) is a bonus from the retailer, never from the label: it changes from one shop to the next and is gone once the preorder window closes.

Our Birthday comes in 5 versions, among them COLORING BOOK, METAL KEYRING, CARTOON BOOK, and PHOTOBOOK. The tracklist does not change from one version to the next: only the box, the photocards and the artwork do. The declared contents of COLORING BOOK match the other versions: the database records no difference in items.

This is an official edition: bought from an authorised retailer, it counts towards the Hanteo and Circle charts, which measure physical sales in South Korea. No EAN is recorded here. The EAN is the 13-digit barcode that names one precise version: it is the safest check before buying.
