It’s paper. Just like most other copy paper. The difference is that this paper was poorly packaged so each and every inside team was not sealed but in an opened cover. I prefer eac team to be sealed. Sealed Paper works better in the Florida humidity.
I have used Staples Multipurpose Paper for years and it is GREAT! I like this new form of that but they have reduced the brightness from 96 to 94 and that is a negative to me. The still have the 96 brightness but the charge a lot more for that.
