A safe deposit box is a secure storage container located within a bank or financial institution. It is used by individuals and businesses to store valuable items such as jewelry, important documents, and other assets. Access to these boxes is restricted to the owner and authorized individuals, ensuring that the contents remain safe from theft or damage. To rent a safe deposit box, customers typically pay an annual fee, which varies based on the box size and the bank's policies. The boxes are housed in a vault, and access is granted through a key or a combination, providing an extra layer of security for the stored items.
