Review (4/5): Very pretty finish
These are made with a clever design to ensure you are putting them on correctly. According to the enclosed instructions, you always wear them so that the heart part of the backs are on top when you slide them onto the post of your earrings. This insures that the weight of the earring pulls the heart against your ear which, in turn, counterbalances the earring and holds it securely against your ear. They're really lightweight, but they work well. I tried them on my heaviest earrings to see just how securely these backs hold and they do not disappoint. Even using them with lighter earrings you can tell they are held much more tightly and upright against your ear. They are designed so you can tighten or loosen the clasp on them so they're adjusted just the way you want them. A friend gave me a set of these for Christmas and I liked them so I bought more for myself and a couple more sets for my sisters to try. I'm happy that this set is 18K gold plated sterling silver so I won't have any problems with allergies. They are a great idea and they have a very pretty finish.
