A more thorough explanation:

A safe-deposit company is a type of depositary where individuals or institutions can leave money or valuable items for safekeeping. It is a company that provides secure storage facilities for its customers.

For example, if someone wants to keep their jewelry or important documents safe, they can rent a safe deposit box from a safe-deposit company. The company will provide a secure vault or room where the customer can store their items.

Safe-deposit companies are often used by individuals, businesses, and organizations to store important documents, such as wills, deeds, and contracts. They are also used to store valuable items, such as jewelry, rare coins, and artwork.

Overall, safe-deposit companies provide a secure and convenient way for people to store their valuable items and important documents.
