Children's Earrings: Sterling Silver 5mm White Pearl Earrings with Screw Backs

White, simulated pearl earrings for children from perhaps age 7 or 8, measuring 5mm, set in sterling silver with safety screw backs.  Please note the screwbacks on these earrings have changed.  Instead of screwing to tight, they don't have an end point and you can keep screwing.  With these new backs, you screw them on, pull back on them and they lock into place.  They can only be removed by unscrewing manually.
