Sun & Moon Collection! I hope you love it just as much as I do :) All posts are stainless steel, hypoallergenic, and nickel-free. Every pair is unique as it is handmade and will vary compared to the listed photos. Care instructions: Polymer clay is very durable, but not impossible to break. Remove when sleeping, showering, or swimming. Store safely away from other jewelry to avoid scratches on the clay surface. If earrings get dirty, use a soft wet cloth to gently wipe the surface.
