Great for classroom. Wipe off better than any other sheet protectors. Heavy Duty and nice plastic covers. This is a GREAT PRODUCT for the use of wipe off markers.Use in classroon to help childern to learn to write better.
I use page protectors a lot. I would not buy these again. There are other brands that are much better. These are wrinkled and the heavy weight ones also wrinkled and not very thick. They do the job but I don't like them at all.
