Sizes and prices range as per the style of the earrings. All earrings are lead, nickel, and cadmium free. All posts are made of stainless steel or gold-plated stainless steel. Please ask for clip-ons in Order Notes if you would like this option. Please note that earrings will have some variance in patterns due to the nature of polymer clay earring production - so the pair you get will truly be one-of-a-kind.
