For years I had a huge wallet that took up a lot of room in my purse and was always stuffed with receipts, change and all manner of outdated cards and junk. Not to mention how hard it was to struggle my ID out of the little plastic pocket when I needed to hand it over at the airport, when buying adult beverages, etc.
So in the spirit of making life a little easier, I got a mini accordion card holder so now I only have the cards I actually need/use and no room to load it up with junk! :). It folds open so each card is very easy to get out and use!
