These are good quality sheet protectors at a great price. I wish that staples sold the BULK quantity of their matte finish sheet protectors in store and not just online. I prefer the finish of those for the binders I was creating.
I have been writing short stories on various topics for my grandkids age 4 and 6 during this pandemic. I inserted the pages into the sleeves before taking the stories to their homes for them to practice reading. These sleeves protected the pages from snacks and spills creases and tears. Afterwards the stories were inserted into a notebook to be read again and again. Theses sleeves are not flimsy. They hold each page in place and sturdy enough to hold and read either by child or adult.
Adequate sturdiness for most applications as for printed pages but not for onionskin hype pages. Hope stronger sheets were available. Sheets fit well into 3-ring binders.
