Postogon box works alongside an app, allowing users to post letters as well as receive letters from family and friends. The app will allow the user to choose who they’re sending their letters to, add friends and see the time zones they are in. Designed for students living away from their home country and features a delay messaging system in which the letter is received at the same time that it was sent in the other time zone. The user will get a notification they have received a letter but will not be able to open it yet, bringing back the anticipation and excitement of waiting for mail to be delivered. Received letters will be printed out automatically once it reaches the correct time for recipients to enjoy.
