The Staples brand 110 lb card stock is thick but not stiff. I would personally rate it closer to 90 lb card stock. The ivory is a bit yellow in hue. but from reading other reviews I was prepared for this and am happy with the color tone. It matches well with the Staples ivory invitation envelopes. I've purchased card stock labeled 110 lb weight from various places and each company has its own idea of what 110 lb weight means from flimsy to stiff. Some of those purchases have been costly mistakes with no thanks to the industry for useless labeling requirements. The Staples brand 110 lb card stock is usable for my needs (making cards) but is not of the thickness and stiffness I expect from the labeled weight.
