I have found these to be awkward fi use. Hard to put papers into them when they are hanging. Fall off the tracks and they cause papers to bend and makes them a mess.
Won’t hold other folders inside like pendiflex folders do. Only holds letter size papers. I needed just 3 or 4 expandable pendiflex folders to hold similar themed folders of papers. Couldn’t find them so bought these instead but they don’t do the trick.
