The cutest earrings I've seen in a while.
Color: 07.Jul, Color: 07.Jul
We were so happy to get these beautiful and cute silver stud butterfly earrings. The colored CZ let us customize the color to personal preference, which let us pick the perfect option. I really like the silver setting. It is quite well done, and looks far more premium and higher quality than the low price would lead you to believe.
One thing I really like about these earrings is the size. These ended up being the perfect size, and made for a very cute look. I honestly think these might become the new daily-wear earrings. They look fantastic.
Included are the earrings, a pouch, and two styles of backing. Both backing options were very easy to use, and held the earrings securely. The stud was of good quality, and plated in silver along the whole stud. It is difficult to tell for sure, but this seems like the plating was well done. I think these should hold up well over time.
The studs are a little on the long side, but no discomfort was had wearing them. Honestly, I thought it made it easier to put them on. Though, they might not be a good one to wear sleeping or something.
It is easy to recommend these super cute earrings. They will be worn frequently, come in a variety of colors, and are well made. I am very happy with them.

These are very pretty. The perfect size for any age ear. Really girly. They don't hurt the ears and they are not too heavy. Nice and light.
