All earring hardware is nickel free and hypoallergenic.
Earring hardware is set with a strong jewelry glue, but please be cautious when putting them on and taking them off to avoid wearing out the glue.
While clay earrings are pretty durable, they can break. Store earrings in the box/baggie that they are delivered in and be sure to never throw them down or into a purse/bag without being cautious.
Jewelry is water resistant but should not be submerged underwater for a long period of time.
To clean, wipe jewelry off with a clean cloth.
