Cut from heavy gauge brass - this thinner brass makes them much more comfortable to wear weight wise. 1.5 inches tall and 1 inches wide. 18 inch gold plated chain. To care for your custom brass piece, wipe with a smooth cloth to remove fingerprints and oils that could tarnish the metal. If tarnish sets in, treat it like other fine jewelery and use a bit of gentle brass cleaner - follow instructions on the cleaner you purchase.
