These are thinner than regular manilla folders but for holding papers in an file drawer they work just fine. To lable them I would suggest white stickers. Wtiting on the dark tabs makes it hard to read.
I use these in my law office. I try to be as environmentally friendly as I can so these 100% post consumer recycled folders are just what we need. They are a bit flimsy but they just sit in a file cabinet with papers in them so no need for over- engineering. I buy them regularly even though they may be more expensive than standard because it is worth saving some oxygen for my kids.
LOVE this product! the dark coloring doesn't bother me a bit although it may bother some who are not as flexible and planet conscious. it's strong durable and equally as functional as customary file folders. I'll buy this again and am telling ALL my friends/associates.
