Made of titanium
Titanium is the most ideal metal if you have any allergy to nickel or are sensitive to most earrings. Titanium is a solid metal that is not mixed with any other metals. Titanium is water and tarnish-resistant so it won't change color!
Protect your earrings by avoiding contact with chlorinated or salty water as well as perfumes or creams. Store them in a cool, dry place when you're not wearing them.
