This is the minimalistic HuMn wallet with RFID–blocking, aircraft-grade aluminum (or carbon fiber). Its main purpose? To relieve the use of wallets over time, so that they are soon reduced to a sliver, if they even exist anymore at all in the coming future. Its design is rather simple: attach multiple plates (even just one) to the band that holds them all together, and store credit cards and cash between the plates, simply opening them using your thumbs. And after being funded on KickStarter for $295,402, it seems worthwhile. But is it really worth your money — quite literally, since as a wallet, it would be holding it?
