I like this paper because its heavier weight (24 lb) allows for back-to-back printing without see-through from the other side. It is also quite bright. It's a bit pricey compared to thinner stock but I think worth it. The 50% recycled is a bonus.
I wondered about the quality of a recycled copy paper but it is of excellent weight and brightness. Bought for everyday use but it seriously would be appropriate when used for more professional purposes (business college professional correspondence etc.)
