We love titanium posts. They are a high quality, cost effective option for wearing all of our gold ends. They are specifically implant grade titanium which is the highest standard available for piercing jewelry.
All of our threadless ends are compatible with both our 16g or 18g threadless posts so you can wear them in pretty much any ear piercing. Threadless posts come with a fixed disk back. The disk sizes are 3/32" (2.5mm) for 18g and 5/32" (4mm) for 16g.
If you are unsure of the sizes needed it is never a bad idea to consult a professional piercer to confirm both gauge (post thickness) and length for your piercing. Professionals in your area can be found by visiting www.safepiercing.org.
