The Staples cards are a good price and easy use but not so easy to separate. Also something in the texture makes my printer jam over and over. The Avery labels pop apart with a snap! and rarely jam my machine.
Thinking they were similar products I selected these over the Avery "Clean Edge" business cards to save a couple of bucks and was disappointed. These cards are not terrible but I found them somewhat difficult to remove from the sheet. Once removed the perforations along the edges were readily visible unlike the Avery which are surprisingly clean.
I use these to print up business cards advertising my store and my furniture-assembly service. I've tried several brands of card stock and this holds its shape best while going through the printer reducing jams & misfeeds. Also because the cards don't separate until one deliberately creases along a perforation I can carry sheets of the cards to a destination - much less fuss than carrying a stack of cards.
