A "도장" (seal) is a tool used to create an impression on paper or other materials, often made from materials like wood, stone, or metal. It typically features a carved design or characters that represent a person's name, title, or organization. Seals are commonly used in official documents to signify authenticity and approval. In many cultures, including Korea, seals hold significant cultural importance. They are often used in legal documents, contracts, and artwork. The practice of using seals dates back thousands of years and continues to be a symbol of trust and authority in various contexts today.
