I know it's a cardholder, but I bought it to use as a minimalist wallet. It can hold about 5 regular credit cards, maybe 6 if they don't have an embossed card number and cardholder's name. I bought 3 packs of rubber credit card inserts and attached one to each side of the case, each with 2-3 extra cards that I use frequently. So far it works great. There are no curved cards and it fits in the front pocket without much bulging.
