DyknaszGlow in the Dark Industrial Barbell 16G Surgical Steel Industrial Piercing Jewelry for Women Men Cartilage Earring Helix Rings 1 1/2 Inch 38mm, 8 Pieces

Some of them aren't functional in the balls done and screw so you can't use it on your piercing but the ones that work are great.

I can't even take the balls off of some. My husband has tried to. I can only use 3 out of 8 industrial bars.

Didn't like,returned.

Didn't glow in the dark

They're super cute and look just like the picture I may get them in another color! Used the ball on one of them to replace the ball that fell off on another jewelry and that fits as well though the balls are bigger lol
