A pop clasp was developed in response to European Union requirements that a clasp open automatically under a tension of 27 newtons. Automatic opening of the clasp significantly reduces the choke hazard that exists with the typical teething necklace. The European Union goes one step further and requires that the string be very strong and not break before it is subjected to a tension o f90 newtons. The sale of teething necklaces in Europe is regulated by laws within the European Union that require a pop clasp. Regardless of the type clasp used on a necklace, all the warnings applicable to a baby teething necklace apply.
