A mailbox is a type of cabinet or container where mail and other small items can be stored. Mailboxes are often used in houses, apartments, offices, or other buildings to store mail that has been delivered through the letterbox or through another delivery method. Mailboxes are often made of steel, brass, or plastic and are designed to be strong and durable. Some mailboxes also have a lock or cylinder to secure the mail. Mailboxes can be used to store mail until it can be collected or to prevent mail from getting lost or damaged. They can also be used to sort and organize mail so that it is easy to find when needed.
