Great value for personal and professional use. I change the message on my cards frequently so printing by the 100s isn't a good option. Printing 10-20 at a time on an inkjet is much more economical. They tear easily after folding a couple of times. An occasional "tag" that remains is easy to pick off. B&W or color text and color images (logo clip art) show up well. Not so good for a high res photo but that's not an intended use. If things settle down there's the Staples Copy and Print Center for slick sharp-edged cards. Until then these are optimal.
I use these business card blanks to make cards for myself and all my committee members to hand out when we go out talking to people about our Relay For Life events. I also enclose a card in each note I send out to Team Captains and Committee members. The Staples brand card blanks are comparable to other name brands are a lot less expensive. The sheets of cards work well with my injet printer and they produce excellent looking multi color business cards that are easy to read and look professionaly printed.
