"Are the earrings heavy?"
Not at all! That is the beauty of polymer clay, it is extremely lightweight. As light as a feather, really.
"Are the earrings sensitivity friendly?"
Yes! I work really hard to research at length the earring components I'm using. All findings (the part that goes in the ear) are hypoallergenic and nickel free. Each listing has the material of the findings listed out. There are some pieces that use brass, but that is usually only on the decorative pieces/charms, not the findings. If an item contains brass it will be specifically labeled as such due to brass being a more sensitive metal to tarnishing.
"How do I care for my earrings?"
❋ While polymer clay is both durable and flexible, I do not recommend bending or testing the durability. Earrings should still be handled with care.
❋ Store earrings in a cool dry place.
❋ Avoid damaging chemicals and use only a damp cloth for cleaning.
❋ Remove earrings before swimming and bathing.
