The 16 gauge 2mm skin tone disc is made from316L stainless steel with enamel coating. Please note that 2mm is pretty much the smallest end you could put on a 16g barbell. That’s great for hiding, but could be a problem if you have concerns about it pulling through. These will fit most any 16 gauge internally threaded straight barbell or labret. We cannot guarantee compatibility with curved barbells. Choose your color below.
