It is a wierd 8-ream case (not 10). Don't know of any other manufacturers offering an 8-case ream. On the box it says it's the brightest copy paper at a brightness of 94 but I have a (Staples) copy paper box previously bought that has a 96 brightness. Maybe there are no other copy paper companies producint a higher brightness than 94 but I doubt it. Maybe it is the "COPY PAPER" classification that makes 94 the highest and above that it becomes "LASER PRINTER" paper? Wierd. But the paper is nice. Copies just fine.
