BTS Jungkook Birthday Popup Store 〈24-Hour Kkukkku Sauna〉

This birthday popup store was designed by combining the fan nickname “Kkukkku” with the uniquely Korean jjimjilbang (sauna) concept, creating a playful and charming universe unique to Jungkook.

Under the theme of a “24-Hour Sauna,” the space aimed to offer fans a cozy, everyday-like environment. From merchandise and VMD to interactive content, the character “Kkukkku” in sauna uniform was applied throughout to deliver a fully immersive fan experience.
