As the title says, the black wore off and has turned to a bronze color. Still a good piece and does it’s job, just wished it stayed the color that I wanted.
Pros
I love it
Cons
The blue coloring on the flags may bleed onto the metal over time
They are OK. It is more for me than anyone. Next time I would get a color other than Black. The only way you can tell it has the Blue Line Flag is to get up really close to the valve to see it. It just looks like normal caps from more than a few feet away.
