I used these before and have been working with them for decades now. I originally got them just for stamp collection and preservation was key to my choice. But after using them for photography portfolios and then my teacher wife has made use for showcasing the students work! She says she had always been offered flimsy quality that reflected too much gloss or fell off the bulletin boards. But these are heavy enough that they have been used and reused which makes them more green and less wasteful. It’s worth buying in bulk too because you end up using them for more than what we planned for and the price was better too!
The Staples Heavyweight Sheet Protectors are really good at protecting your forms and the holes that the binder prongs go into are practically unbreakable. Clear view makes it easy to see the forms and the price and value was good for a 100-sheet box. Won't run out very soon.
They are excellent easy to put documents in visibly clear remains straight and neat and above all can be re-used many times.I am very happy with them and I guess that’s a recommendation.
