When it comes to children's earrings for your little girl, you may be curious about what, exactly, screw back earrings are.
They feature a normal post which goes through the ear. The post is threaded, as is the back (internally.) It not only holds the earrings safely in place, but also offers protection from the pointy end of the post.
Unlike traditional backs that can pop off with little fingers fiddling with them or when clothing is removed over the head which can pull off a regular back, screw backs can be screwed on tightly to ensure they stay in place. This means the earrings cannot fall out and become lost.
