A wax seal is a decorative emblem made from melted wax, often used to secure and authenticate documents. Traditionally, a stamp or signet ring is pressed into the wax before it hardens, leaving an impression that signifies the sender's identity or authority. This practice dates back to ancient civilizations and was commonly used in medieval Europe. Wax seals are typically made from a blend of wax and resin, which allows for a smooth application and a clear impression. They are often associated with formal correspondence, such as letters and invitations, and can add a touch of elegance to personal or business communications.
