Check out these stainless, surgical steel plugs adorned with the classic Batman symbol! These stainless steel, screw-fit plugs are available in multiple gauges, featuring a screw-on, stainless steel backing for securing these puppies through those gaping holes in your earlobes. These Batman plugs are made from the highest quality material, and the result of superior workmanship. These are absolutely the cat’s pajamas. And Batman agrees with this.(Comes in pairs) 316 Stainless 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%, 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.” Please make sure that you are selecting the right size – we cannot accept exchanges and refunds on body piercings. That stuff was in your body! Ewww!
