White paper. It is 20lb. Good for printing. I would buy it again. Just did not like he easy rebate system (that is why I gave it four stars). But the paper itself is very good.
In general they're working well for me so far. I'm using them for general printing and copying for school and office work. I also donated them to a school and school teachers loved them. The quality is just perfect for general school copying. For my personal experience sometimes they got jammed. I was not sure what was the cause. It could be the printer or it could be the paper. I got paper jammed with other brands too. Anyway I'm glad that Staples was able to give them away for free after rebate. Thank you Staples!
