The 5 tab folders just aren't as useful as the 3 tab. Though there are 5 of them each tab is a bit too small for a mailing label or to write directly onto.
The paper on these file folders is a bit thinner than I am used to but it does save space in a drawer. I prefer the 3 tab but 5 tab did work well for the work I was doing.
We use these folders as client folders at a homeless shelter; they get a high level of use and handling and do not stand up to use over time like they once did. However they are still worth the purchase at volume pricing; we can just toss the ones that break down and replace them. We use the thicker colored file folders for other non-client administrative files that we want to maintain for the long term without replacing.
