Screwback earrings for babies and children have always been popular. Parents know exactly what they want for their children. Use the screwback by gently turning the back clockwise on the earring post. "DO NOT KEEP TURNING OR USE FORCE" The threading will catch the back and give it a strong and secure grip. As long as they are left alone they will not become loose on their own. These earrings are comfortable to sleep in and there is no need to take them off. This collection was designed for baby and toddler.
