Bought this for my daughter as a reward for doing her homework every night.  When it arrived she was delighted with how it looks and wanted to wear it right away.  First off, the clasps were not tight enough for me to be sure they would stay on well, but I told her to just be careful and see how they were.  The first time she wore them all day the clasp on one side broke off and since the metal is very soft I couldn't repair them well enough for them to stay on.

Just for the record, my daughter has other clip on earrings that work fine, with no worries about them coming off.  This is not some cheap $5 pair of earrings.  Very disappointed.  Contacted the seller, Bling Jewelry, and they suggested I bring the earrings to a jewelry shop to be fixed...  Not worth your money if you don't want to check your earrings every five minutes to see if they've come off.  Not recommended.
