I purchased two packages of the Staples Ivovy Card Stock due to the fact it was buy one get one free. I used this card stock to create invitations to several special events for family members. The sheets loaded into the printer easily and did not jam or get stuck. The ink printed on the cards wilthout smearing or feeling wet. The invitations looked professional done and elegant. Each card has a smooth finish. i was able to cut the cards using a paper cutter and the cards did not have any rough or rigid edges. I was very impressed with how the cards came out.
I am a big fan of card stock for several purposes. Initially I used it for table tents for groups that have ongoing meetings. (I downloaded a table tent format that prints on both sides of the folded tent.) People are always impressed and they work perfectly. Lately I have also been using this project whenever I am printing something to go into plastic sleeves for binders or into the clear cover itself. It provides a nice clean print job and the stiffness makes "stuffing" the sleeve or binder cover a snap.
Been using Staples card stock for a while. I make my own greeting cards make posters for community events etc. Works willl with my inkjet printer. Holds and displays colors well. Easily folds in half for greeting cards.
