Pros: cute and so so so useful
Cons: none for me!
Mine is a different color but I love this necklace. love it love it love it. especially with baby wearing this was a great plaything for my son while being carried and it kept him occupied and not chewing on the carrier straps. It's wonderful for nursing as well since it keeps his hands busy instead of picking at my nose, lips, pulling hair, my shirt... etc.
If you're looking for fashion, this may not be it. If you want cute and totally functional. Get one!
