Hi im thinking of buying some Industrial Jewelry online but im not sure about the measurements. My recipt for my piercing says a 14g 1/4 barbell was used.
From what I see on the site, pick the 14GA 11/4 option since it's long enough to go through the top of your ear. Seems there was a little typo on the receipt your piercer gave you. The mm measurements next to each of the sizing options refer to the diameter of the balls on either side. Hope that helped!
