Stainless Steel Bent Barbells - All of the steel basic bent barbells in our collection of basic piercing jewelry are internally-threaded and made from 316L ASTM F-138 implant-grade stainless steel. The high-quality material composition of these stainless steel bent barbells and their internal threading allow them to be inserted more easily during the piercing process. Since internally-threaded jewelry won\'t scrape a new fistula upon insertion the same way that externally-threaded jewelry can if not inserted carefully, piercings also tend to heal faster and better when our high-quality stainless steel bent barbells are used as starter jewelry. Our stainless steel bent barbells are ideally suited for a wide variety of piercings, including eyebrow piercings, belly button piercings, VCH piercings, PA piercings, tragus piercings, and many others.
