Internally Threaded

Blackline Internally Threaded Body Jewellery consists of threaded body jewellery items that have the threads on the balls and accessories, rather than the bars themselves. The bar is the part of the jewellery that is pushed through the piercing, and so conventional jewellery with threads on the bars, can cause tiny tears in the flesh and irritate the piercing. With Internally Threaded Jewellery, the bars do not have threads on either end, and are completely smooth.
