Always committed to high quality products, customer satisfaction is our greatest affirmation and support. Product size: 4.5cm x 4.5cm material: made of high quality copper. The 18K gold coating does not contain nickel and lead and is not easy to fade. More importantly, even on metal, we added zircon to keep the brooch shining all the time. I believe it will bring you good luck, so this brooch is not only suitable for you, but also the perfect gift for ladies and friends.
