Carré Royal wallets and cardholders are part of the Jansiaux line, which offer leather made super-soft from vegetable tanning. Though based in Paris, the brand’s workshop is cozily situated in the hilly countryside of southwestern France. Since the 1950s, when its founders settled in the region famous for its handmade leather and wool traditions, the company has been toiling to carry out a vision of elegant and finely crafted leather goods. The result is a casual but refined collection of practical pieces that are anything but square.
