The protectors are great good weight and easy to put into binders for keeping fragile documents or clippings. I'd certainly recommend. Suggestion: make the Staples logo on the side of each protector less intrusive -- smaller type non-bold etc. It tends to distract from the contents.
I found this to be flimsy and tore easily at the seam when inserting two sheets of standard copy paper into the sleeve. I will buy a heavier sheet protector next time.
