印 (Seal) is a traditional tool used in East Asian cultures, particularly in China, Japan, and Korea, to mark documents and artworks. Typically made from materials like stone, wood, or metal, seals are engraved with characters or symbols that represent the owner's name or a specific meaning. They serve as a signature, providing authenticity and authority to the documents they mark. In addition to their practical use, seals are also considered an art form. The process of carving a seal involves skillful craftsmanship, and the resulting impressions can be visually striking. Collectors often appreciate seals for their historical significance and aesthetic value, making them an important part of East Asian culture.
