The threadless post is made with implant grade steel
Threadless ends are made to be worn in threadless posts. For these ends, we recommend these posts.
More threadless jewelry can be found here.
Threadless jewelry is a push pin technology. The removeable end (dark grey) has a slightly curved pin. This pin straightens out when inserted into the shaft (light grey). The resulting spring tension force holds the two pieces together securely.
