The Batman Symbol 316L Surgical Steel Stud Earrings are based on DC Comics' ever popular Batman and feature the now ubiquitous Batman symbol! Say, that guy is pretty popular these days. Something about some super smash hit movie trilogy...but I don't get that because George Clooney and 'Ahhhnold' were only in one Batman movie! Somebody will have to fill me in at some point! In the mean time, you should really think about getting these super fine Batman Symbol 316L Steel Stud Earrings which are made from high quality 316L bio-steel! That makes it sound really awesome, doesn't it?(Comes in pairs)316 Stainless Surgical Steel is the preferred steel where bio-compatibility is required (such as body implants and piercings). The L means that the carbon content of the alloy is below 0.03 percent, which reduces the sensitization effect. 316 steel has .08 Max carbon content while 316L has a .03 Max carbon content. Stainless steel does not contain, corrode, or rust as easily as ordinary steel. Though it will not oxidize or turn black, it is still not stain-proof.We cannot accept exchanges and refunds on body piercings. That stuff was in your body! Ewww!
