Masks are objects worn on the face to conceal or alter one's appearance. They can be made from various materials, including paper, plastic, or fabric, and are often used in celebrations, performances, or rituals. Masks serve different purposes, such as entertainment, cultural expression, or protection. In many cultures, masks hold significant meaning and are used in traditional ceremonies. For example, African tribal masks are often used in rituals to connect with ancestors or spirits. In modern contexts, masks are also popular during events like Halloween or Carnival, where people wear them to embody different characters or themes.
