This is a gem for those of us who need to carry all our information cards and references to doctors, vets, insurance, as well as credit cards.  It is one of the more sophisticated organizers and compact. Usually I deal with a small one that begins to bulge as soon as you have a dozen cards in there.  Its sleek lines are like one's checkbook and looks professional.  Would recommend this to anyone seeking something a little nicer than the small black card holders so often sold.
