Our 14k solid gold threaded ends fit an 18g/16g straight threaded post. Threaded jewelry is sold as three separate pieces and threaded ends require a straight post & ball or disc back in order to be worn. If you need the complete item, be sure to purchase a straight post as well as a ball or disc back.
If you are unsure of the sizes needed it is never a bad idea to consult a professional piercer to confirm both gauge (thickness) and diameter for your piercing. Professionals in your area can be found by visiting www.safepiercing.org.
