New Artpaxy wallet
Color: Black, Style: Retro, Color: Black, Style: Retro
Too soon to tell. Does hold All my cards. good looking wallet. However, once all cards are in place, very stiff and thick. As I said, Time will tell. Hope it will soften with use. Saved my old one ...Just in case. Patty

Very roomy
Color: Coffee, Style: Modern
It's great. I feel secure with the RFID, the leather is soft and looks great. It has many pockets for cards so that I can spread out my cards. This makes it slim in my pocket. This is a very nice wallet; I recommend this as a great gift or a replacement for yourself.
