15x12mm big and 1mm thick leverback earwires, made of stainless surgical steel.
Sold per pkg of 2 pairs (4 earwires).

Nickel safe

Very strong, stainless and tarnish resistant

Surgical steel is highly tarnish resistant and a great alternative to sterling silver. Wires made of steel will also keep their shape better than many other, softer metals.
If you need jewelry findings that last and does not cost too much, surgical steel is a great choice.
