Details on Oakley Grenade Pin Keychains?

Saw this listing and have never seen this display piece before.

These look awesome to me, but does anyone know the story/details behind them? The listing doesn't provide much in terms of context.

They came in two colourways: Black/red and Grey. They're keyrings/keychains which came out in 2009.......
