I bought his paper after running out in the midst of a school project that was due the day after I ran out. I didn't expect my history project to require 50 sheets of paper...After about an hour of nagging my dad to drive me to office depot for printer paper. Luckily we found it quickly and I made it home in time to finish my project. I still have plenty of this paper left today and I still use it for many things. Ive started getting lazy and begun just typing all of my school assignments instead of writing them as I usually did. This is 8 and a half inches by 11 inches white paper. This was a box of ten 500sheet packs of paper. However, this is kind of on the low quality side of paper as in kind of thin. It's pretty nice for class assignments and things like that, but if you plan on making a card for somebody or making some nice origami you should try getting something a bit better. All in all this is a great product and I will buy it again when I run out for sure!
