Titanium Belly Rings
Titanium is the fourth most abundant structural metal on earth. The nickel content is less than 0.05% by mass making it ideal for those sensitive to nickel. Titanium is also bio-compatible and is totally resistant to body fluids. The light refracting off the oxidised surface allows an incredible range of colours and it is extremely lightweight, scratch-resistant, highly-polished and very tough (three times stronger than steel).
Tummy Toys have a small selection of titanium belly rings available for purchase.
