PININ Navel Piercing with External Thread, Rainbow

The Pinin piercing is designed as a belly button piercing. It is made from ASTM F-136 titanium, which is hypoallergenic thanks to its high biocompatibility, minimising the risk of skin irritation. The rainbow colour is created through an anodisation process, which ensures the shade remains stable without the use of additional dyes. The external thread allows for easy handling when putting the piercing in or taking it out.

Titanium Material and Finish

The piercing is made from implant-grade ASTM F-136 titanium, which is commonly used in the medical field for its high biocompatibility. It is very well tolerated by the body and does not cause allergic reactions. The rainbow surface is not the result of dyeing, but of anodisation. This is a controlled electrochemical surface oxidation process that creates a thin layer of oxide on the surface of the titanium. Its thickness determines the resulting colour, which is durable and will not peel off.
