Use this Surgical Steel 0 Gauge flanged earlet for a 0 gauge ear piercing or you can stretch your 4 or 2 gauge piercing to a 0 gauge using a taper. Surgical Steel earlets come complete with o-ring. Our Earlets are flanged which means they look better and will not fall out. A flanged earlet will not pull through your ear. It stays flush against the lobe of the ear.
