I purchased these earrings for my granddaughter who is 3 1/2 years old. They were too big for her little ear lobes so now I wear them. (I bought the 4mm for my granddaughter and they are the perfect size for her.  I will also do a review on the 4mm earrings.)

The reason I love these earrings: the posts are 14k and do not irritate me sensitive ears, they sparkle beautifully, the screw-on backs prevent the earrings from getting too tight on your ear lobes while sleeping or talking on the phone, and if you do happen to lose one it won't cost a fortune to replace them. Just when you think of it, re-tighten the earring backs to ensure the are secure.  Hope this helps you with your purchase.
