I've been using these sheet protectors & find them to be made very well. I dropped one of my books off the table & not one sheet was affected from being damaged.
There was a variety of qty packages as well as density to choose from which gives the shopper an opportunity to fit the budget and style from which to choose.
I made 2 binders for a co-workers 2 children. "SCHOOL DAYS" I printed on colored labels for each year & placed them on each sheet protector. All the information on the front & a pocket to place awards report cards and other special things from each year of school for each child. It was a Secret Santa Gift and the Co-Worker LOVED it so!!
