BTS has released a "Learn! Korean with BTS & TinyTAN" study kit, aimed at helping fans (ARMY) learn the Korean language through interactive tools, exclusive video content and official merchandise. The launch taps into surging global interest in Korean, driven largely by BTS's own popularity, the wider K-pop wave, and last year's animated film KPop Demon Hunters.

The $139 flagship bundle includes six study books covering hangul, everyday vocabulary and K-pop terminology, alongside a MotiPen that plays pronunciations and exclusive BTS voice clips, plus QR-linked video lessons and collectible extras such as a BTS-themed Gonggi game set. Two further kits are available: a $100 four-book, four-language package with a speaking pen, and a $92.24 TinyTAN chibi-style edition with flashcards and posters. According to Duolingo, US-based Korean learners rose 22% in 2025 compared with 2024, making it the second most popular language studied after Chinese.
