Personal seals are unique symbols or designs used by individuals to authenticate documents or signify ownership. Historically, they were often made from wax and stamped onto important papers, serving a similar purpose to a signature. Personal seals can include initials, family crests, or custom designs, and they are still used in some cultures today. In modern times, personal seals can be created using various materials, including rubber or metal, and are often used for artistic or decorative purposes. They can also be found in digital formats, allowing for electronic signatures in documents. Personal seals reflect individuality and can carry personal or cultural significance.
