Stacking card holder

If your like me, and don't like to carry an actual wallet with you, this might help your cards last longer. The nice feature of this is that it can stack cards in different height, so it's easier to see the cards, and get the one you want.

Just push your cards in place and they are secured. When you want to use them, push them all up with your thumb, and then release. Cards should now be nicely stacked so that you can select the one you want. Once your ready, just push them back.

Please report any issues with it. I noticed that an old, slightly bend card, with high emboss, did not work as a first card, since the embossed text could prevent the card from dropping in place.
