These are great starter folders for MRs and economically friendly. They are sturdy and work great with avery dividers.Very nice folders, with easy to use fasteners on each side. I really like that I can attach the paperwork easily, so that it doesn't slip out. (Some papers I merely push the metal fastener through, and others I quickly punch a hole with a single hole hand squeeze punch, since it's easy enough to eyeball the spacing...) I use this feature to sort within the folder, which is handy. They are very sturdy, and have held up well. I love the different colors, allowing me to instantly grab what I want, without necessarily having to read the tab. Much much handier than standard manila folders.
