I like to use these folders all the time for any paperwork I have. They are very durable and always look nice. I have used them for many years when I worked in offices because they held a lot of documents and all the different colors make it easy to have meeting notes and distinguish which group it belongs to. They are also great for all of the church groups I belong to.
These folders are nice if you're looking for something simple basic and good for a business atmosphere where you don't want like anything too colorful. Construction is okay they get worn down over time fairly quickly and you can expect that they won't last forever. If you want to buy a folder for long term repeated use it would definitely be worth your time to splurge on something that's made of plastic and is built to last. They also get pretty beat up and dirty with repeated use so not great for presentation/meeting use more than twice or so.
We use these for events and workshops. The construction is good and labels stick well to the front. In the colder months static becomes an issue trying to insert papers and I would like to see them in different colors but they serve the purpose and look professional.
