This is a nice wallet. Pretty much the same size as all the others. I like the thumb slot to help push out a card. However...do NOT put your card in that slot the way it is pictured on the item's sale page. Common sense should tell you that if you can SEE the RFID chip in the thumb slot, then it is not protected by the RFID blocking. So, you do have to make sure you always put your card in the same way, with the chip toward the top (covered) portion of that slot. But as long as you do that, the slot is nice. I would have liked an ID slot with a clear window so I wouldn't have to take it out to show it to anyone. But I guess since some states have RFID in their licenses too, many RFID wallets don't have those. I don't know how many cards you could reasonably squeeze into the 4 slots (plus one for money), but I think if you have more than it can handle, you shouldn't be shopping for a minimalist wallet in the first place.
