All earring are handmade made from a Non-Toxic PVC based medium called Polymer Clay. So they are super light on the ear, with stainless steel post or Nickel free clip on backings used.
Caring For Earrings:
Store in a carrier to avoid damage or easily broken. Even though polymer clay is durable and strong it still needs to be cared for correctly because it can be easily broken with improper use and storage.
Use a damp cloth to wipe in-between wears, if you find there are marks that don't come off you can use a small amount of rubbing alcohol on a cotton pad and wipe gently to remove the mark.
