DH's work has a clear desk policy so at the end of every day he has to put everything from his desk in a locker. He is a bit sad because he likes to have pics of the children on his desk and other personal things. I there a fold up desk tray or folder that you can open up and put on your desk and it has all your pics etc and then can just fold away at end of day and put in your locker? (And if not can someone invent one please).
