The silver is made of fine silver 99.9% pure silver, which is purer than sterling silver. This silver is ecofriendly as it is recycled from old movie tins. It´s actually recycled twice since I make these from my discarded silver projects. Ear wires are made of high quality titanium, great for kids, healing holes or people with metal allergy, even people who have allergic reactions to anything less than 18 K gold usually have no problems.
The earrings come with a pair of clear rubber backings. MADE ON DEMAND, takes me up to 5 workdays.
