I love these earrings!!  I've bought many pairs over the years and they're just awesome.  I have several piercings in each ear, so they're the perfect size for multiples.  I have never lost a stone or had any defect with them, and I wear them 24/7 through workouts, showers, sleeping, etc.  Small enough to leave in my cartilage overnight and they don't bother me at all. Super affordable, so it's no big deal if I lose one, and I usually have an extra pair on hand.  If they get dull from extended wear or hair product, a quick soak and scrub in warm soapy water shines them right up.
