The jewelry is machined from solid titanium (ASTM F136 6Al-4V ELI). Their patented “snap-together” threadless system is an effective alternative to internally-threaded jewelry and is currently in wide use by many body piercers.
Ends and Posts are sold separately so unless you are just buying a replacement, you will need to buy a post and an end (gem, ball, other shapes, etc.) So If you are buying a gem, ball, or any kind of end, you will also need a post to go with it. Same goes for posts, if you buy a post, you will also need to buy some kind of end to go with it. Let us know if you have any questions. Thanks!
