The smallest cardholder I've ever made or owned: the Ellis. This little guy fits between 2-6 cards!! A great front pocket wallet, and also a great option for someone who has been carrying loose cards around in their pocket. I've watched many folks trade in their binder clips, broccoli rubber bands, and hair ties for this wallet. It's one I've returned to time and time again in my own personal collection. Can't go wrong with an Ellis.
