Stunning. These 12g threaded 5-32 solid 18k yellow gold balls work beautifully for nipple piercings. Level up your nipple jewelry with these - 12g threaded and compatible with our 12g threaded barbells. PLEASE REMEMBER - these ends are sold INDIVIDUALLY - so if you need enough for one barbell, you’ll need (2) ends. Two barbells? (4) ends. Need threaded barbells in addition to your ends? You can find those right here!
