Glitzy ball to fit 1.2 mm and 1.6 mm bars. Wear it where you like it best, but only in fully healed piercings. Please note that this item is not suitable for intra-oral piercings as it is epoxy-coated for adhesion and smoothness. This means it is not autoclavable and prone to scratches, so please keep tweezers and forceps away from it. Who'd want to use these brute tools on such a beauty anyway?
