I ran out of Staples clear heavyweight sheet protectors and bought these as a replacement. The new ones are not as heavy and are just a tiny bit smaller than the older Staples protectors. It is very difficult to push a piece of paper into these these skimpy flimsy things.
This is the same product I have purchased previously however they are harder to open to put the sheets inside. They were produced with a different type of plastic.
These sheet protectors are strong and work very well with written material. However they are not clear but hazy and do not show off photos very well. The listing as clear is misleading. The box for model #13860 lists them as non-glare. This is true and accurate. True Clear sheet protectors are item #489131 model # 31866
