These are very pretty. I wore them for the first time yesterday, and one fell off my ear 5 times in an hour. I was trying on tops, so I was in a dressing room. I finally decided to press the metal area of the clasp to see if that would make a difference. The metal was very hard & withstood the pressure I applied(I used all the strength in my fingers)... had to do this 3-4 times, but it did help. The next few hours, no problem.
