I love that they are BPA free and I don't have to worry about baby chewing on them. They are made for baby but mommy can wear and never have to worry about leaving babies teething toy at home and you know it will stay on your neck and not end up on the floor. I also love that they come in a lot of colors. They will also make great baby shower gift for a new mommy. The food grade silicone really feels good on his sore gums and helps relieve some of the crankiness. Whoever came up with the idea of thee was pure genius! These necklaces are probably one of the most useful baby items I have ever owned.
