C-Line All-Purpose Document Sorter, 2.5 x 23.5 Inch, Blue (30526)

I have used this as a teacher and it has saved me so much time. When you have 30 students and need to file or return papers, this makes the tasks easy and fast. I plan to use it this summer to organize my own paperwork. The price is a great value because you will use it every year. It is strong and durable. I highly recommend this tool especially for teachers.
