No need for mail or important internal documents to go astray. If you are responsible for distributing mail to other colleagues or departments you can use this pigeon hole method to sort it. There's no need to leave mail on people's desks, just slot it on the letter tray so everyone can have a tidy desk. The letter trays are part of the Avery Desktop Range and come in four colours so you can match to your other office accessories. The black tray is made from 100% recycled plastic.
