Great value and super cute!
Color: Gold, Size: 30-40-50mm, Color: Gold, Size: 30-40-50mm
These earrings are a yellow gold which I like, and they’ve held up really well the past few days in the shower and with daily wear. These feel high quality and as long as you arent rough with the clasps, these should last you a long time. These are affordable for the quality. I don’t think these will tarnish, and they haven’t lost any shine. The ones in the picture are the smallest size, but I love the others too. They are comfortable to wear and very light weight, whereas others I’ve tried have been heavy or not sturdy enough for daily wear. I would definitely recommend buying these!

Lovely earrings
Color: Silver, Size: 20-30-40mm
These earrings are thicker than what I wanted but they are so lovely and packaged so nicely that I am not going to return them. I will gift them to someone instead.

Very comfortable and light weight
Color: Gold, Size: 30-40-50mm
For what I would spend for one pair, I got three. Not knowing what size I wanted, I chose the three pack and I am glad that I did. I generally only wear stud earrings because of the weight and I don't like things dangling and touching me. So far, I have only used the smallest pair and like them. They are big for me but for most people probably wouldn't feel all that large. I am not certain that I will use the medium or large pairs but maybe some day I will feel dangerous. If you aren't sure what size you will feel comfortable with, I would suggest this package and try them all to see what your style might be. They are a good value and are light weight.
