They are exactly the type we have used in the past and were readily available in the local store making for less stress and a timelier completion of the job!!!!
I have purchase heavy duty legal size legal folder from Staples for over twenty years. This product was my only choice when I went in to the Kenwood store last week. The files folders are flimsy and tear easily. I drive past two Staple's locations on my commute to and from work. I don't really feel a need to incur shipping costs because you can't stock a store with ordinary items.
Price wise these folders were a good deal. I didn't realize they were legal size until I started to organize them - decided to keep them based on current events. If I needed folders for heavy duty use I would not choose these. For tracking geneology documents for my family they are perfect.
