Couldn't afford the deluxe 19-inch replica of Serenity? Now Quantum Mechanix is unveiling a keychain version for just $10, going up for sale on their website later today. And you can win a one-of-a-kind chrome-plated version.

For more details on the Firefly keychain — and info on how you can win the chrome-plated model — check out Quantum Mechanix's site. The keychain doesn't ship until March, but you can order it now.
