Modern Lulu polymer clay earrings are hand-cut and finished with hypoallergenic titanium posts & aluminum/bronze push backs. The clay components are water resistant and make for a super lightweight earring. Due to the handmade nature of these earrings, they are all unique and may vary slightly from the photos.   ◆ CARE ◆ Polymer clay is a water resistant and flexible material, but please avoid direct contact with water and try not to bend them. To clean the polymer components, use a damp cloth/q-tip dipped in acetone if the earrings are matte. If the earring has a shiny coating, use a cloth/ q-tip with a little water to clean.   ◆ SHIPPING ◆ Orders are typically shipped between 1-3 business days after purchase. You should receive your package within 2 days after receiving the shipping confirmation email if you choose the lowest cost shipping method at checkout (USPS First Class Shipping).
