Nothing is so aged and sweet as a pure copper monolith. We admit to a little patina as it wears on the skin, but we love it! 7 3mm (larger character) limit, 9 1.5mm (smaller character limit.) We will contact you about your order to verify the number/letter sequence. Slight variations as this is a handmade item. Warm up your day with the play of light on this sleek and spicy number! Choose stainless, bronze, or copper colored ball chain in 2 lengths.
