First boxes purchased were great - this last batch however was not scored all the way thru. They ripped when trying to remove the cover or try to release the sides. Very disappointed
The HD corrugated cardboard files boxes are stable and strong. They stack well.Even though there is not a rail you can hang files. The files will not slide but I think a layer of packing tape to smooth the edge will do it. I ordered the heavy duty file boxes because I had the tru red plastic file boxes by IRIS and the plastic was still gassing off after a month. My lungs and face were burning from it. The IRIS boxes are not water proof because there is a hole to put the sliders on therefore the HD file boxes are the best choice.
