All earrings are made of polymer clay, which is a water-resistant, super light material. Pieces are delicate and should not be bent or dropped. Make up or other dirt can be removed from clay earrings by GENTLY going over dirty spots with a q-tip dipped in rubbing alcohol or transparent acetone (not colored).
Metal components may tarnish over time if exposed to water, humidity and oil from the skin, but can be easily cleaned with a soft jewelry cloth and/or tarnish remover.
As with most jewellery, keep away from perfumes, nail polishes, hairspray or any other solvents as it can cause damage over time. Keep earrings from direct heat or very hot/humid places. Keep away from children as the small pieces could be ingested.
