I don't have a very elaborate filing system so use these for monthly filing and sorting. I'd say they're fine for that use but expect they'd likely not hold up to daily use if you use them as I do. Essentially I use them for archiving project documents and I think they're ideal for that.
very cheaply made. Don't expect them to last long. I'm disappointed and do not want to give them to clients so they will go to waste. I actually had a client hand them back to me and say they don't want it.
