There are small keychain and credit card combos that can hold multiple cards. It's big, about the size of a normal wallet. Not a replacement for your everyday wallet. (For example, my husband has a smaller version that he uses to commute to the gym, carrying keys and a few cards). So as a wallet replacement, it's pretty good. If you put $20 in one of the "card" slots for an emergency and don't need real money for any purpose, it will completely replace your old school purse. RFID blocking. Well equipped. But quite large, as already mentioned.
