These are an old staple but even after all these years nothing compares. They are sturdy and durable. They last for years ; standing up to filing cabinets boxes and warehouse storage. And they are the only thing for those large oversized files.
I have used these folders for years. Unfortunately I got used to using them when they were provided by a law firm; now that I have to buy them myself at nearly two dollars each the cost stings a little. Still I have tried to make the switch to manila folders to save money and trees but I can't beat the sturdiness of the pressboard for court travel and repeated shoving into and removing from filing cabinets. I'll probably continue buying them at least until a comparable but more eco-friendly product is available.
