These teething necklaces are like nothing else on the market. They aren't strung on the entire necklace, so they won't snag long hair. The silicone beads are free of chemicals and BPA. As for the wooden beads, they are finished with beeswax and olive oil. They can be conditioned at home with coconut oil to keep them nice and smooth. The necklaces are handmade in Birmingham, Alabama. Indie & Chic provides employment for mom's in their community, which is something we can totally get behind.
