WHAT DO YOU MEAN BY HYPOALLERGENIC?
Since some people are allergic to nickel, the EU nickel directive regulates how much nickel may be released onto the skin per week. For earrings, these are a maximum of 0.2 micrograms per square centimeter per week (i.e. 0.2 millionth of a gram). All Studex studs and earrings fall well below this allowable value and are thus nickel-safe and allergy free. In fact, all Studex studs and hoops are hypoallergenic, nickel-safe, lead-, cadmium- and cobalt-free.
