If you fear losing or forgetting an important piece of paper by putting it in a drawer, these trays are perfect for you! This is what I did in my office and it works great. I lined them up side by side so I can easily label each tray and see what’s in it. I have one for IN, OUT, and ONGOING PROJECTS. Quick tip, if you have the space, line them side by side so you can label the back of the tray.
