Haven't used the paper yet but the outside wrapper is so flimsy that it ripped open as I placed the package on the seat of the car - no I didn't throw it or drop it.
This box was priced very well. It is the standard copy paper used most often for normal high volume typical business and personal copying. The carton is made of strong durable cardboard making it easy to transport. The individual reams are also covered in a nicely strong paper stock allowing the sheets to remain "new" even if stored for months. There is no yellowing that occurs after many months. The paper is excellent quality and performs well. It holds color well and does not jam the printer and copier.
