Unidirectional post box is a one-direction mechanism that allows to place the parcel inside the customer home but never to take it back, preventing for package theft. The mechanism is simple, effective and there is no need for any key, password or use of technologies that can be time consuming. The system needs to be fixed to the front wall where a previous window should be opened. When the mailman closes the mailbox, the mail will enter the house automatically. If someone else wants to open the box to steal, the delivery is already safe. Also, the system allows multiple deliveries.
