We recommend 18g 3/8" or 18g 5/16" flat back studs or hoops for nose piercings. Depending on the thickness of the skin on your nose you may need to size up or down lengthwise. If you have a fresh nose piercing and would like a hoop, remember to wait until your nose is fully healed to change your jewelry. If you have any questions don't be shy!
