I am very pleased with this standing vertical open file that can sit on a desk or counter, while taking very little space. ( 10.5”x 12”) and allowing up to 10 shelves for sorting papers, or mailings or magazines, or whatever you want to have readily available.  I chose to have 1 less shelf at the bottom and 1 less shelf at the top, so I could have more height on 2 of the shelves. Thus, the number of shelves is up to you. I would recommend this vertical file organizer.
