Last year I decided it would be a good idea to pick up a holder for my personal blogging 'business' cards. Most of the places I checked didn't carry them, and the ones that did (engraving shops) usually dealt with more ornate holders. I didn't want anything too pretentious.
Then a couple days after Christmas we were walking through a store when I happened to stumble across this great little gadget. It's a plastic case with two heavy elastic bands attached to the cap at one end; just pull the cap to get to the cards. And, as a bonus, the first one I saw just happened to match perfectly. (Looking at this photo reminds me I have to have updated ones made with my new number).
It only cost me about six bucks and does the job really well. Good score huh?
