I bought these sheet protectors for my grandson's report on the California missions. We were able to print his report on standard paper. It was easy to put the paper into the sleeve.
I use these protector sheets to cover my cookbook pages. (I cut out recipes and pictures glue them on paper insert into protector sheets and sort into large notebooks.) I have also used them for covering sheets of photographs.
These sheet protectors already have the three holes punched in them so you don't have to put holes in the papers you're inserting. This saves time and all the holes are already lined up for you. No time wasted trying to put the three holes in your paper and not getting them all even. They keep everything organized. Very attractive design and they are lightweight but sturdy. Love them!
