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 and size due to the nature of polymer clay earring production - so the pair you get will truly be one-of-a-kind.
