Mine are a 16 according to th eguy who did them... I didnt even know enough to ask~ so when I was looking at jewlery at different sites I noticed that there were some that offered different sizes. So I called and asked him what the gauge was and he said 16. Great now you tell me that I might have troubles. Is there something I should do to maybe increase the size or should I go to another piercer and see about getting a 14 gauge stud to stretch them? Or should I leave them well enough alone since I have had no problems? Here I was thinking they were pretty standard and then I found out on the jewlery sites they arent. Oh happy happy joy joy. lol
