These plastic sheet protectors keep important documents from being torn getting wet or bent. I put them in three hole binders to keep my important papers organized and looking like new. I can't live without these protectors. They are great for teachers like myself. It is great to have the hard copies to back up my files on the jump drive.
I do genealogy research and have lots of binders full of family group sheets; census records; birth death and marriage records; and family photos. These are precious documents that would be a shame to lose or allow to deteriorate. The easy open box allows me to grab one at a time to insert my papers and stick them in the binder. Easy use and archival quality make it easy to preserve my family history. I love these sheet protectors.
