Hoop earrings brass, nickel free. Dimension: 6cm or 4 cm Sold by pair Brass, unlike gold, is a metal that can oxidize over time. To avoid and delay this oxidation, I recommend that you do not sleep with your jewels, and not expose them to water. If, however, they come to tarnish, you can revive their color by cleaning them with toothpaste or lemon. Sends in follow-up mail within 1 to 3 days following your order. Thank you for your visit !
