These Oiled Indigo wallets and card cases from Friday & River are handmade in the USA out of indigo-dyed nubuck leather, and will develop a unique patina with age, just like, well, anything else that’s colored with indigo dye. Also, like anything else that’s colored with indigo dye, the wallets and cases will leave a faint trace of blue on the things they touch. And if there was ever a way to show the world just how big of a menswear nerd you are, it’s with indigo-stained dollar bills. I’m sure the cashier at 7-11 will be very impressed.
