Three Hearts silicone and beech wood teething necklaces are designed to make mom feel that she has not given up jewelry in fear that baby could get hurt. Mommy can still feel stylish and fun with our necklaces as they are designed to replicate real jewelry rather than just a teething toy for baby. They are utilitarian for the modern parents, fun, stylish, and doubles as a fully functional teether toy for baby. Our necklaces are made with 100% certified food grade, non-toxic silicone (BPA, cadmium, phthalates, PVC and lead free). We also use untreated beech wood chew rings. Each and every piece is handmade with love.
