191I got one of these Mighty Wallets as a gift, and used it for years:https://mightywallet.shop/Super thin, cheap, but very flexy and durable. Made out of Tyvek ®, so they don't tear, and can only be cut.I never would have bought it for myself, but totally loved it. I had the one with the sheet music on it. Asked about constantly.It still works, but I switched to an even smaller wallet for travel last year, and never went back.
kerble is right.
