Card Kingdom is a card shop on the fourth floor of a building on Sinchon-ro 254 in Mapo-gu, Seoul, near Ahyeon Station. It sells Yu-Gi-Oh, Pokemon, and One Piece cards, with Korean Yu-Gi-Oh singles ranging from old sets to recent releases. Card supplies and a dueling space are also available on site. The shop draws crowds on weekdays and fills with visitors buying albums on Saturdays, and popular card packs sometimes sell out.
