Butterfly Card From American Express

The butterfly card from American Express is a foldable card that fits into a small silver compartment that doubles as a key chain. The card actually folds in half to fit inside. You can either pull out the half with the magnetic swipe strip or you can remove the card and unfold it to full size. It’s a great idea to make carrying the card more convenient and it’s perfect for all those small clutch bags. It’s available to all of their Gold Card holders.
