I've used this paper for several years. There are several staples papers that I find very useful. The double sided matte inkjet paper is fine for greeting cards as you can print on both sides. The multipurpose paper is suitable for business documents and other presentation uses as well.
I was skeptical to get this paper because I normally go for the branded ones (like HP) and I haven't tried using store brands. I tried a ream and it compares really well with other branded paper. Smooth just the right thickness and ink does not bleed. I do a lot of printing and I could say that this is one of the best I've tried so far. I don't think I would ever switch back to the more pricey branded ones ever again. It has very good quality and best for my printing needs at a reasonable price. I ordered 3 boxes more :)
I have use this paper before and been satisfied with it. What makes it special was the offer from Staples to get a rebate that equaled paying for only one ream of paper while getting the entire case for free !!!!!
