Exactly as advertised with nice attention to detail.
This is exactly what it says it is!  I really appreciate the jump ring used to hold this together.  I am going to be using this on a keychain and the jump ring is really solid without a seam.  This is important so that it doesn't come apart and get lost.  This came exactly as described.  I do with there was a no necklace/key chain option but that's not a big deal.  The necklace came in a nice little pouch and a sticker.  The rings are exactly what I expected.  Colors are vivid, feels nice in the hand.  Fun to play with.  Abuse testing has started.  We shall see how well they hold up under use!
