Constructed of vegetable-tanned leather, waxed-linen thread, and solid-brass hardware in different finishes, our Magnetic Keychain embodies quality and strength at the first sight and after many years of use. As with all our leather goods, these keychains will continue to look better with age. The hardware included is all solid brass and come in an array of finishes; nickel, matte nickel, classic brass, and antique brass. The split key ring included matches the other hardware and will complete your style. The spring gate O-ring allows you to add key rings or attach your keychain to another object. The magnet inside the leather is rated at 13 pounds of pulling force, which is reduced by the leather but still plenty to keep your keys and other small objects attached to a metal surface.
