Suni's House in Geumcheon-gu recreates a small living space used by industrial workers in the old Guro complex. The November 2–30, 2026 dalgona stamp program lists two Monday-to-Saturday sessions, 13:30–14:30 and 15:30–16:30. Participants watch a video about industrial workers, complete a stamp mission through the exhibits and receive a dalgona kit. The fee is KRW 1,000 per person, payable by card on site. Independent visiting is free but does not include a guide. Preschool children need a guardian. Inquiries: 02-830-8426.
