I have been using the Staples Standard Sheet Protectors for several years and I am totally satisfied with them. I am putting together a scrap book for my granddaughter's school years of playing sports and other activities. I also use the protectors for my recipes. I put them in a binder and they don't get spilled on while I am using the recipe. I am in the process of typing my recipes from the card files and inserting them in the sheet protectors.
