Light reflects off every angle of the 3mm glitterball top. Comes in size 16 gauge with a 5/16 (8mm) wearable length. Internally threaded so you can securely wear it in your labret, helix, or other cartilage piercings. The post is made from 316L stainless steel and the top is made of epoxy, so this piece should be worn in healed piercings only. Sold individually.
