Really nicely made necklace with a very easy pop off clasp, but not too easy because it hasn’t fallen off. I would say it *helps* with teething because my son is pulling on his ears less, and I’m giving him significantly less teething tablets for pain. Plus it’s super cute. I love the rainbow/ombré one I chose, and will probably get one for myself to match. Overall, I would say it’s a good buy and worth a try!
