Threaders made of work-hardened, patina'ed and tumble-polished copper, closed with a matching patina'ed copper wire spring. They are available in two gauges: a large 4g size, and medium-sized 6g size. The 4g size fits through most 00g or larger tunnels (i.e. tunnels with internal diameter of 5.5mm or more); the 6g size will fit through most 2g or larger tunnels (internal diameter of 4mm or more). They are designed to fit through tunnels in gauged piercings or bare stretched lobes and measure approximately 2" in diameter. Chose your size with the drop-down menu at checkout.
These are heavier than my aluminium hoops and are great for those who like to feel a bit of weight with their threaders/ear weights. Each 4g hoop weighs approximately 19 grams, while the 6g hoop weighs about 12 grams. In the photos, I am modelling the 4g hoops.
Named after the great inventor and showman, Nikolai Tesla. Here's a quick video showing how to take off and put on my Tesla coil hoops.
