I love these earrings of Boccia. I bought a pair of these great earrings already a few years ago - unfortunately I have these removed during sports and promptly lost. Fortunately, my husband bought later and they gave me. I'm totally happy about it because I've missed so painfully in the meantime. This time my explanation of why I find these earrings so great: - The earrings are simple yet high-quality look and are so for all occasions and events wearable. - They are made of titanium, that is: I get no intolerance reactions even when I let times overnight there and it asleep. When I wear them accidentally in the shower or while swimming, the material is not changed thereby and not stained from. The earrings are very light, you can hardly feel that you are wearing. Why I forgot also frequently take them off. But as I said it has no adverse effect on the ear or earring. - The closure is to act super and very firm to close, so that they practically can not be lost. There is a danger only when it decreases. ;-) I wear the earrings best every day and do not want to miss it. So an absolute recommendation from me!
