They also contain a non-toxic bitter coating to discourage children from swallowing them and prevent ingestion. In my opinion, the best part is their Color Alert technology which activates seconds after making contact with saliva. A blue dye will be released leaving the mouth and tongue blue which helps alert parents or caregivers to act fast.
