I received the set I ordered and I can say I am very pleased with it. The colors of the pearls match perfectly and the size is perfect, not too small and not too large (the pearls are 7mm, not really 7.5mm). The posts are pretty secured, but as with any butterfly post earrings you have to check your ears from time to time (especially if you keep the earrings on 24 hours a day for several days in a row).
The pearls look pretty elegant on the ear and I am pleased with the range of colors in the set. I can definitely see me wearing them often. For the price I payed, I definitely plan on taking this set with me on vacations when I go to Europe, Central America and Mexico.
I also plan on ordering 2 more sets to give as gifts since I was so pleased with the set I have received. You really can not beat the price and I personally feel that you get a lot for the money.
