I bought these for my students to use in the class for a variety of things. They use them to complete daily activities. They hold up well. I used these last year and liked them so much I went back and bought more for this school year.
Ever since I bought a poly folder I make it a point to buy poly cover notebooks. It is very durable wipes clean and it last longer than a cardboard cover. It is perfect for my elementary and middle school age kids.
