I have been using Pendaflex-brand hanging folders for over 20 years long before they were reinforced. Files that were used heavily broke the hanging folders. Reinforced models held up much better. I tried these Staples versions of hanging folders and have been pleasantly surprised. They match the quality of my existing Pendaflex folders for a much lower price and represent a much better value. Although Pendaflex has evolved to offer a spring-loaded hanging clasp it is not very effective. Although Pendaflex offers slightly different colors than Staples-branded folders and I use the colors to categorize my files I will stick with Staples.
There isn't really much to say about these hanging folders except that they are really good quality and I love the variety of colors. I need them to organize my files.
The metal hangers are so thin they bend when sliding the files in the cabinet. Thin like a paperclip. The brackets literally bend over and tangle or break off. It defeats the purpose of a hanging file. I'll be looking for another source. I used these for long term storage as they won't hold up to daily use.
