These pink double flared tunnels are made from Zirconia ceramic. These look and feel like a thin-walled pair of glass tunnels, except they're so difficult to break. We're excited to be one of the first shops to have them. They feature a Mohs hardness around 8.0 and high fracture toughness, making it virtually scratch-proof in everyday conditions. It's been used extensively in prosthetic joint replacements and dental implants because of it's strength and biocompatibility. Zirconia ceramic is hypoallergenic and chemically inert with a non-porous surface. Choose your size below.
