Security bag

A security bag is a special type of bag that is used for important documents and money because it has extra locks and security features to make it harder for someone to steal the contents. It usually has a zipper that is protected by a combination lock or keyed lock, and it may also have extra straps or clips that make it harder to open. It also usually has an extra layer of protection such as a hard plastic liner or even a waterproof material. Security bags are used by banks and other businesses to transport and store important documents and currency.
