All threaded and threadless ends are sold as ends only and ship without posts. If you do not know how to install either style, what post length or gauge you need, or need help installing your piece feel free to contact me and I can help you find a local piercer who can make sure the piece fits properly and is installed correctly.
I am not responsible for lost or broken pieces due to improper installation and cannot take returns on any body jewelry.
