I received these earrings over a week ago.  Let me tell you they are beautiful!  They are small (pay attention to the dimensions given they are accurate), but they sparkle!  The clasps are tight; the backs flip open so you can slip the post through the earlobe and snap shut right into the back of the hoop.  No fuss,  no muss.  I had no problem with either earring.  I have slept with them in every night and washed my hair with them in every day since.  I have not had one pop out or unhinge once.  I would definitely buy these earrings again.  For $15 you bet!
