The listing, Faux pearl necklaces has ended.
I'm not really sure where these are from or what, if any, retail value they have, but I found them when I was going through some old things.
I have one that I use, I like it a lot.
They fit a little looser than a choker.
The clasp in the back is kind of tricky, but once you get the hang of it, they're very easy to take on and off.
