We use only the highest-quality, phthalate-free, federally approved silicone in our Teething Bling™ line. The material is non-toxic, latex-free, food–safe, even dishwasher-friendly! It is the same silicone used in many other popular teething products and SGS test reports are available upon request. Although we stress that this is adult jewelry not intended for children to wear, all of our pendants come with a breakaway clasp as an added safety feature.
