Natural & Organic Flesh Tunnels are made from a variety of materials such as bone, horn, wood, coral and gemstones. They are breathable, comfortable and beautiful. These Flesh Tunnels are for use in healed, stretched piercings, such as the Stretched Earlobe. Flesh Tunnels are available in sizes 3mm to 51mm (US 8g to 2"). For help with sizing please read our guide. For more info about stretching and the different types of Flesh Tunnels please read our Body Jewellery Guide. Organic and Natural Flesh Tunnels are all unique and so there can be slight variations in colour and shape. They should not be exposed to harsh chemicals such as bleach, or to high temperatures. A natural oil such as Jojoba or coconut oil can be used to treat the surface of wood and horn flesh tunnels. Please read our Materials Guide for info about Natural & Organic Flesh Tunnels.
