I have been using these folders for a long time and they are very good construction. We have 8 filing cabinets on the first floor 3 on the second and 12 on the third and we use these folders in all of them. They seem to last a long time and are very sturdy. We have tried the recycled ones however I do not like them as much as they seem to be flimsy. I have tried other folders from other carriers and feel you get a good value and a good price with the staples brand products. We purchase all of our office products from staples.
