Munudang Seojeom sells books on the ocean, shipping, and maritime transport, and sits in a back alley of Nampo-dong near Jagalchi Market. Its stock is mainly textbooks for pilot and navigator study along with other sea-related books, continuing the line of the old Nampo-dong bookstores. Subway and bus stops are close, so it is easy to reach by public transport. It is smaller than the former Nampo-dong bookstores and is now a small back-alley bookshop.
