Goldtone Faux Pearl design Solid alloy metal; has a little weight to them. This is a design inspired piece. It is not an authentic MIU MIU item; it did not come from the company or any MIU MIU affiliates. As with any brooch, always handle a pin and a needle gently. The needles are not ‘firm’ making it easy to connect under the metal shield cap. Always use care! ☺️ sd’s AAA: as always; as is, sales final, and if I can answer, ask questions!
