I ordered this silicone stopper because unfortunately fall on my silver earrings the associated closures miraculously or otherwise disappear. Of course, they are found usually not again and if it runs quite stupid, this is also the earring lost - just annoying.
But not anymore. Was a really great idea. The stopper fit all my earrings without slipping. Now the risk is to lose the beautiful silver earrings eradicated and I am reassured.
