16 Gauge Titanium Internally Threaded Flatbacks
16 gauge barbell which is a flat back. This is titanium coated surgical steel. The rhinestones are internally threaded. I have 10 different colors from: Clear, Sapphire Blue, Black, Peridot green, Topaz orange, Medium Pink, Aqua Blue, Red, Light Pink, and AB clear. I ordered 20 gauge but got 16 gauge instead.
