To start with, are these the best made folders I have ever used? The answer is no. However, for my use, they are great! I use a lot of folders to hold my large collection electronic service manuals. (I mean A LOT OF FOLDERS!) Each one does not get a lot of use and these folders will hold up just fine for all the years I will need or want them. If I wanted folders to be carried on the road in a truck for daily use, of course, I would use a more substantial folder. Even though they are not the BEST MADE folders I have ever used, they are still stronger then what I actually require for my application. For applications such as mine or for a kids final turn in project, these folders are more then adequate. The price is right. EVERYTHING IS RELATIVE! For this reason, I give these folders a 5 star rating. I don't need a better made folder at a higher price for my application. (However, one caution. These are not accordion type "expandable" folders. I don't use these when I have a manual 3/4 inches thick. For them I use an "expandable" folder.)
