I would reccommend this to all new business owners. They make a good impression and people are less likely to lose or throw out. The only problem I had was getting to card on right....it is not easy if your hands shake.
I use these in the home mainly to organize business cards that I've collected. I am able to easily find the numbers and addresses for doctors and dentists landscapers and retailers that I frequently use. They also work wonderfully for family pictures that are too small to frame but I still want to display. My refridgerator is no longer boring.
