Nice light large hoops
Bought as a replacement for a set of my favorite earrings. These are a close second. The clasp on one isn’t quite as tight as the other, but they stay on well

Style and fit
The pic makes them look oval, but they are actually round. That would be fine, but they are also a bit difficult to open and close.

Nice stainless steel hoops
I ordered these hoops for myself, but i wound up giving them to my granddaughter. She loves them and wears them everyday. Made well, and very sturdy.

Cheap in all respects
I mean, how much can I complain about stainless earrings that don't even last three months? The hoop was fine, but the clasp wouldn't stay closed and then snapped off within three months. Worth the price? Kinda on the fence about that.
