I bought this necklace a month or two ago after seeing the cute scrollwork.  It was only $15 at the time so it was a good deal.  I wouldn't say it was flat.  it's more like it's hollow out.  so it wraps around the side but there's nothing on the back.  and no it doesn't rotate because it isn't round so i've never had a problem with it flipping around and showing the back.

I really like it because the scrollwork looks intricate.  I like it just as much after i got it.  It is sharply defined and you can see all the curls.  It is a little on the big side being 2" or 2.5" long so I wouldn't wear it as earrings.  I guess it had to be a bit big so all the curls can be clear.
