Hello, the Nipple Suckers Mini may have such a low material safety score because P.V.C may contain phthalates. Phthalates may be dangerous.
Why Are Phthalates Dangerous?
Shown to damage the liver, kidneys, lungs and reproductive systems in animal studies, phthalates can be absorbed through the skin or inhaled. Scientists at government agencies in both the U.S. and Canada agree that exposure to the chemicals could cause a wide range of health and reproductive problems in people.
Not to be a dark cloud, I just thought it could be an explanation.
Have fun everyone!
