This end will fit most of these posts
that are 18g/16g/14g.
NeoMetal does not use any adhesives or glues on any opal/stone set into a flat surface like the bezel set ends, and the opal/stone may spin within the setting. This is not considered a defect. Each piece is put through a stress test to ensure the crimping of the setting is wide enough to hold the opal/stone in place.
These are for straight pieces of jewelry (barbells or labrets) made by NEOMETAL only.
They can connect to any of the labret posts in this listing, but sizes smaller than 2.5mm are not recommended for 16g and 14g shafts.
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.
