Sweet slime-envelop’d Cthulhu, that’s a lot of wallets! Most of them looking like clones of one of two basic layouts. Hard to believe they all can get so much kickstarter support.
Personally I don’t like too-skinny wallets any more than I like too-skinny phones, (or for that matter too-skinny sex partners). Here is the wallet I carry, holds as much stuff as a mini tool bag and built hell for stout.
