Reliable Paper I Keep Coming Back To.
Size: 500 Sheets (20lb)
’ve been buying this paper for the second year now, and it’s been consistently great. It works well for everyday printing—no jams, good quality, and nice bright white color.
It’s not the thickest paper, but for the price it does exactly what I need for home and office use. Definitely a reliable and affordable option I’ll keep repurchasing.

Nice feeling paper.

Very nice paper. It has a good smooth feel to it on top of a nice weight. I haven’t had any problems with it getting jammed in the printer.

Exactly As Advertised
Size: 500 Sheets (20lb)
What can you say about printer paper? It needs to be the right size, the right weight, the right color. This fits all those requirements perfectly. I only take away one star because it is so Basic, just like the title says: it is printer/typing paper and it does a great job of that. It does not cost an arm and a leg, like some paper does. I have run half a ream through my printer so far and no jams or misfeeds.
