The earrings are made of polymer clay, they are ultra light on the ear, on a surgical steel support, nickel-free stud earrings with a silicone stopper. Will not cause irritation, your lobes will thank you! All buckles are designed and made by hand in France, they are unique and may vary slightly in color and shape. Polymer clay is a slightly flexible material. The buckle is covered with a light layer of resin so that it is more robust and shiny. The earrings should be stored in a clean, dry place, keep them away from oils, creams and perfumes (do not wear in water). Makeup or other dirt can be removed from polymer clay using a damp cloth or tarnish remover (especially for jewelry). If you prefer the same style in another color, send me a message and we can agree on a new design together!
