We’ve seen it before. When it comes to something as simple as a set of keys, we often settle for the most convenient at the time. But after a certain age, generic carabiners with chipped paint and promotional bottle opener keychains not only scratch up the other things in your pocket, they make you look like a kid. Bottom line: a gaudy set of keys can really ruin a wardrobe. Thankfully though, a sleek leather key ring like the ones we’ve featured here can add just the right amount of sophistication you’re looking for.
