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.
