It looked like a 2-year-old stamped the staples logo on cheap plastic pockets since I was using for personal it didn't matter but if this was for work go with something else.
These binder pockets are perfect for adding odd sized items to a binder such a pamphlets smaller booklets sheets of paper that cannot be hole punched due to the material on the sheet and in our case a small electronic (USB) adapter. As stated above these are LARGE and do extend outside the edges of the binder not a problem as long as ones expects this when ordering this item (thank you to others that pointed this out)
