Mukoya Seonmulgage is a local gift shop on the sightseeing route around Donghae’s Mukho Port and Mukho Lighthouse, selling postcards and stickers related to Donghae and Mukho. It displays sea-themed goods, travel souvenirs, and small household items. It is a convenient stop after visiting Dodaebigol Sky Valley, Mukho Lighthouse, and Nongoldam-gil, with a view from white tables and chairs on the sea-facing side. The neatly arranged shelves photograph well, and the view overlooking the sea is a defining feature of the shop.
