Rhodium-plated Alloy on waxed linen cord. Measuring about 40" in length.
Rhodium is a rare, silver-white hard metal in the platinum family. It’s resistant to corrosion and oxidation in moist air — rhodium also increases its durability.
One of the biggest upsides to rhodium plating is it’s nickel-free, making it hypoallergenic. Longevity can depend on one's body chemistry.
