Holds a lot and is a great buy.
Color: Black, Size: Medium - No Mirror
Arrived quickly in a nice box and plastic wrap. Holds a lot, great for travel or every day. Got the black colored one, but they have lots of colors so can easily put gold in one, silver in another and mixed in yet another. Highly recommend!

Safe for sensitive ears
Color: Green, Color: Green
I purchased these earrings to wear on St. Patrick’s Day at work because they’re festive while still looking somewhat professional. I got so many compliments on them! I personally don’t think they look THAT similar to the Van Cleef version but multiple people did ask me if they were authentic. The best thing about these earrings is that they didn’t irritate my sensitive ears or feel heavy throughout the day. I plan on wearing them more often now!
