Although we currently don’t have our own physical bookstore (and we don’t sell books at our office), you can find our books in many major Korean offline bookstores such as Kyobo(교보문고) and YoungPoong(영풍문고). For your information, the Kyobo bookstore in Gwanghwamun (1, Jong-ro, Jongno-gu, Seoul, or Gwanghwamun Station Exit 3) usually has the largest selection. If they don’t have the book you are looking for, you can ask the staff to restock it, and they will have it ready for you within a few days.
