I was very disappointed to find out that this cardstock is more like 65# and NOT 110#. I don't know how Staples can get away with claiming otherwise. If you are looking for heavy cardstock: DO NOT BUY this. (I am a graphic designer & I know cardstock.) The only good thing I can say about it is that it foils well but it is so flimsy that I will have to double up on it in order to use it.
