These earrings are handmade with real pressed flowers encased in resin, they are like wearing a piece of nature. Each piece is one of a kind. Sometimes we will use the same color combination, but no two are exactly alike! All earrings have stainless steel or titanium posts/hooks, which are great for sensitive ears. They come with plastic backings. Multiple items purchased will come packaged together unless otherwise requested. Studs are 12mm. Any questions, please feel free to contact us!
