Nope, that isn't just the flash.
They are normal concave buttons, but they are clear with colored plastic inserts inside them.
I used 4 Pelican Real Arcade Universal controllers to make my control panel, and those are actually just the buttons that came insde them.
I have gotten several inquiries about them lately, and several people looking for where they can find the same style buttons. I don't know where to find buttons like that other than in the Pelican sticks, but if anyone does happen to find them, I too would like to know where.
