Teething is a painful part of a baby’s life. The gums ache and most of the time feels itchy because of growing teeth. This is why teethers were invented. Although some teethers might contain lead and phthalates which are hazardous to baby’s health, the Circus Teether Rings are not only Phthalate and lead-free, but are also PVC and BPA (bisphenol-A) free with FDA compliance too. The teethers are made in the USA using medical grade materials in a class 7 clean room environment. There are 3 teethers in every plastic case of Circus Teether Rings and is safe for hand washing only.
