Select gauge/diameter from the drop down menu. Titanium ion plated 316L surgical steel.
*Some gauges/diameters may require tools (ring openers/closers) to work with. I am unable to remove/reinsert the 10g-1/2" beads by hand. I was able to remove/reinsert the 12g-1/2" and 14g-5/16" pieces by hand with some difficulty (I would imagine some won't be able to do this by hand). All other gauges-diameters were relatively easy to work with.
