these Staples brand sheet protectors work really well for our office and retail application. We have multiple departments that use these in binders to maintain the quality of printed pages for recipes and other necessary documents like instructions and methods of operation.
I use three ring binders for organizational purposes within my office. I keep a lot of hard copies in these binders and rather than have plain paper to tear or bend unbecomingly I chose to use the Staples Standard Sheet Protectors. They keep my work more precise as two sheets fit back to back I never have to worry about having to reinforce the punched holes as these eliminate that need since they are built right into the sides and I have never had one tear our on me! I can see clearly now and seeing is Believing these are the best protectors. I would recommend them to anyone!
I work on genealogy of my paternal and maternal lines with the goal of providing coomplete family tree with all documentation for each of my daughters. I have had special expandable binders made in leather with the family names and my daughters names. I am using the sheet protectors to put all of the documents in these binders to protect them from damage and to have a storage place that is easily shared with other family members. Another way I am using them is for storing historical documents in binders for my research of our town history. Allows me to look up things quickly or take them to meetings well protected in binders without worrying when people want to look through the documents.
