Geometry + Funk + Fashion = these earrings!!! These unique, spunky earrings are made of polymer clay and have a pin earring back made of zinc alloy. They measure 3 inches long and are lightweight. Please see photos for additional size context. They have a standard pin earring back for pierced ears. I have a limited number of this style earring in stock. Due to the handmade nature of this item, there may be slight variations in what you receive, when compared to the listed photos (i.e. extra dots, varying stripes, etc). If you wish to purchase these, I can send you an exact photo of the pair you would receive. Thanks for looking!
