It's a pin. It's a good pin. It's a black pin. I's a sturdy pin. It's an Ibanez pin.
To summarize I'm using these on my ibanez acoustic bass, at least they won't lose their head-pieces when you remove them. Good price, nice finish, I guess it's made of harder material than the original in my guitar, which was also made by Ibanez I guess. I'd buy the same if I need one again.
