Nowadays, a lot of jewelry can rightfully claim to be nickel free, but that doesn’t ensure that there won’t be problems down the line. How is that possible?

In many cases, only the plating alloys of “nickel free jewelry” are actually nickel free (i.e. jewelry plated with rhodium-alloys); meaning the metal below the plating can still contain nickel. This can be a potential hazard because even the tiniest scratch in the plating can allow nickel to come in contact with the skin, thereby causing an allergic reaction. We also have to be aware of the phenomenon of ion flow, a process where nickel can come to the surface as a result of the movement of atoms. For these reasons, a lot of jewelry advertised as being nickel free and hypoallergenic can, in fact, still cause allergic reactions and inflammation in the same way as non-hypoallergenic jewelry.

Our earwires are made of pure Niobium; there is no plating on their surface, which ensures that they're absolutely nickel-free. For your safety, they're also 100% hypoallergenic.
