The charm is exactly what I was hoping for. Not too big and not too small. I had it engraved, which was nice because one of the "other" websites that sold it did not offer that.
My only drawback so far is the chain. It catches on my hair from time to time. It also looks like it has a kink in it sometimes and needs to be smoothed out by hand. I might get a different chain for it later. Otherwise, the length is perfect (and adjustable), and it has a lobster claw catch. And the engraving is beautiful!
