I did not want any heavy wallet in my pocket, which was too clearly visible through my jeans, so I designed this easy cards wallet. Nice about it is the possibility to see which passes are in there. So when you shuffle through the cards you can easily pick the one you need. I used the triangular shape to press the cards out easily. I have been using this design for 4 months now and still like it.
Although my cards never fall out make sure you have enough cards so the triangular clip can keep the cards from falling, because the material does loose some tension after a while.
Amount of cards that can be put: 10 (and some extra paper money for example)
