The Full Moon earrings, despite their size, are lightweight. Each piece is handmade and no two are identical: variations in shape or color make each creation an original work of art. MATERIAL Handmade in polymer clay. The post is made of 925 silver plated with gold, fixed with a technique that does not use any type of glue. Nickel free. DIMENSIONS 5.5 cm x 5.5 cm CARE Apply makeup, perfume, hairspray, etc. before wearing your jewelry and definitely do not wear them in the shower or pool! Polymer clay is a non-toxic material, it bends slightly but breaks if subjected to excessive pressure.
