Description
Upgrade your jewelry game with our Internally Threaded Titanium Tunnels, precision-engineered for performance, hygiene, and style. Available in sizes ranging from 8G to 1 inch, these tunnels are made from implant-grade titanium, offering a lightweight, hypoallergenic, and durable option that’s gentle on sensitive skin.
Each piece features internal threading for smooth, irritation-free insertion—ideal for both stretching freshly gauged lobes and long-term wear in healed piercings. The 5/16" wearable surface ensures a secure, comfortable fit, while 1.8mm flares keep the jewelry in place without over-stressing the tissue.
These tunnels are also fully autoclavable, making them a hygienic choice for professional use or personal stretching kits.
