I wasn't sure what to expect when I ordered the earrings. I knew by looking at various jewelry that there was often a disclaimer that the colors were more vibrant in the picture to enhance their appearance (*hint hint* to those complaining about this upon first seeing them in person) hence why I didn't put high hopes on them. I'm an optimist but image enhancement is a modern day reality. Oh well.
To my delight they were just as beautiful as the image. They are very light weight to the point I forgot I was wearing them until my daughter pointed that fact out when we were laying down for her bedtime story (several hours later). I was initially concerned about them not having backs but with the way the wire is curved they don't slip out. I kept them in until I was ready to turn in myself. They were that awesome! I will be wearing these over vacation in a few weeks since they match all my outfits to a T.
I will most likely use backs while on vacation since it will be taking place in a large amusement park. Besides that, I don't think they're absolutely necessary. May differ from person to person though.
