The 16g ferido cz circular barbell is made from either 316L stainless steel or high polish grade 23 titanium (Ti 6Al-4V ELI ASTM F136) with external threading. The crystals have a thick, crystal clear coating that keeps the gems from falling out. The handmade balls are very consistent in quality, but please don't expect perfect spheres.
