not real heavy duty but I don't need them to be I just want something to organize my papers and this folder does the job. Good price especially as when I bought on sale.
I LOVE office supplies. I have to buy a ton of them for work so i like to make it fun and mix it up here and there. I like these folders because they are two toned and that's fun for me. I also like them because they come in a smaller package - so i wasn't forced to buy an entire box of file folders which happens more often than you'd realize. But the package was substantial enough that while i only needed like five folders i was able to keep some for myself because it was like a twenty four pack or something like that. win!
The Staples Brand Manila Folders are a great bargain for the money. We use a lot a folders and these are the best economical bargain that Staples has to offer.
