Great for business cards
This is a really good and tough product. I originally bought it to use for my trading cards I am making for my books. The trading cards are put on business cards then laminated. The business card protective page is a hair too small for them. I had forced them in, and then tried to get them out. It was not easy tearing the plastic to get out my trading cards. :-)
Visiting cards - carte de visite
I used these for 19-century visiting cards. There are several sizes of these, but the smaller sizes fit well.
