I love the Chrysmela earring backs. They have taken all the worry out of wearing my good earrings as I know the backs will never slip off. These discs are an excellent addition. They snap onto the Chrysmela backing and help to keep earrings, particularly diamond studs, upright instead of drooping down. These are great if your ear holes are a big enlarged from age or if your earrings are heavy and tend to droop forward. For such a reasonable price everyone should get these!
