Just arrived from In Season Jewelry! These were gifted to us in the birthstone of my kids. They have a patented screw back on them that I love! Mainly bc my little one pushes the backs of her earrings WAY too tight and then we have ear issues ! These prevent that from happening and helps my oldest not pull the earrings out during play or when changing clothes (RIP to all those lost earrings!) Nickel free. Hypoallergenic. Child friendly designs (really for all ages!) and they sparkle like crazy! win inseasonjewelry livinglargeinlilly These are one of my FAVES! LTKdayinmylife LTKKids LTKmomlife
