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 our piercing studs and earrings fall well below this allowable value and are thus nickel-safe and allergy free.
In fact, our piercing studs are hypoallergenic, nickel-safe, lead-, cadmium- and cobalt-free!

For our needle piercings, we primarily use Implant-Grade Titanium (ASTM F-136). This is the same material used in medical implants—it is 100% biocompatible, nickel-free, and the safest option for those with sensitive skin or metal allergies.
